Module type XHTML.T_01_01

module type T_01_01 = T

An alias for XHTML 1.1 (for symmetry):


The elements, attributes, attribute types and data types are given names that match the names in the W3C recommendation as closely as allowed by a strict typing discipline and the lexical conventions of O'Caml:

Finite sets of alternatives are mapped to polymorphic variants.

The phantom type is always the most general required by any (supported) version of the standard. Type discipline is enforced by exporting or not-exporting the corresponding constructor.

Attribute Types

type cdata = string 

Character data

type id = string 

A document-unique identifier

type idref = string 

A reference to a document-unique identifier

type idrefs = idref list 

A space-separated list of references to document-unique identifiers

type name = string 

A name with the same character constraints as ID above

type nmtoken = string 

A name composed of only name tokens as defined in XML 1.0

type nmtokens = nmtoken list 

One or more white space separated NMTOKEN values

type pcdata = string 

Processed character data

Data Types

type character = char 

A single character from ISO 10646.

type charset = string 

A character encoding, as per RFC2045 (MIME).

type charsets = charset list 

A space-separated list of character encodings, as per RFC2045 (MIME).

type color = [ `Aqua
| `Black
| `Blue
| `Fuchsia
| `Gray
| `Green
| `Hex of string
| `Lime
| `Maroon
| `Navy
| `Olive
| `Purple
| `RGB of int * int * int
| `Red
| `Silver
| `Teal
| `White
| `Yellow ]

The attribute value type color refers to color definitions as specified in SRGB. A color value may either be a hexadecimal number (prefixed by a hash mark) or one of the following sixteen color names. The color names are case-insensitive.

type contenttype = string 

A media type, as per RFC2045 (MIME).

type contenttypes = contenttype list 

A comma-separated list of media types, as per RFC2045 (MIME).

type coords = string list 

Comma- separated list of coordinates to use in defining areas.

type datetime = string 

Date and time information.

type fpi = string 

A character string representing an SGML Formal Public Identifier.

type frametarget = string 

Frame name used as destination for results of certain actions.

type languagecode = string 

A language code, as per RFC3066.

type length = [ `Percent of int | `Pixels of int ] 

The value may be either in pixels or a percentage of the available horizontal or vertical space. Thus, the value `Percent 50 means half of the available space.

type linktypes = [ `Alternate
| `Appendix
| `Bookmark
| `Chapter
| `Contents
| `Copyright
| `Glossary
| `Help
| `Index
| `Next
| `Prev
| `Section
| `Start
| `Stylesheet
| `Subsection ] list

Authors may use the following recognized link types, listed here with their conventional interpretations. A LinkTypes value refers to a space-separated list of link types. White space characters are not permitted within link types. These link types are case-insensitive, i.e., "Alternate" has the same meaning as "alternate".

User agents, search engines, etc. may interpret these link types in a variety of ways. For example, user agents may provide access to linked documents through a navigation bar.

type mediadesc = [ `All
| `Aural
| `Braille
| `Handheld
| `Print
| `Projection
| `Screen
| `TTY
| `TV ] list

The MediaDesc attribute is a comma-separated list of media descriptors. The following is a list of recognized media descriptors:

Future versions of XHTML may introduce new values and may allow parameterized values. To facilitate the introduction of these extensions, conforming user agents must be able to parse the media attribute value as follows:

  1. The value is a comma-separated list of entries. For example, media="screen, 3d-glasses, print and resolution > 90dpi" is mapped to: "screen", "3d-glasses", "print and resolution > 90dpi".
  2. Each entry is truncated just before the first character that isn't a US ASCII letter [a-zA-Z] (ISO 10646 hex 41-5a, 61-7a), digit [0-9] (hex 30-39), or hyphen-minus (hex 2d). In the example, this gives: "screen", "3d-glasses", "print".
  3. A case-insensitive match is then made with the set of media types defined above. User agents may ignore entries that don't match. In the example we are left with "screen" and "print".

Note. Style sheets may include media-dependent variations within them (e.g., the CSS @media construct). In such cases it may be appropriate to use "media=all".

type multilength = [ `Percent of int | `Pixels of int | `Relative of int ] 

The value may be a Length or a relative length. A relative length has the form "i*", where "i" is an integer. When allotting space among elements competing for that space, user agents allot pixel and percentage lengths first, then divide up remaining available space among relative lengths. Each relative length receives a portion of the available space that is proportional to the integer preceding the "*". The value "*" is equivalent to "1*". Thus, if 60 pixels of space are available after the user agent allots pixel and percentage space, and the competing relative lengths are "1*", "2*", and "3*", the "1*" will be allotted 10 pixels, the "2*" will be allotted 20 pixels, and the "3*" will be allotted 30 pixels.

type multilengths = multilength list 

A comma separated list of items of type MultiLength.

type number = int 

One or more digits.

type pixels = int 

The value is an integer that represents the number of pixels of the canvas (screen, paper). Thus, the value "50" means fifty pixels. For normative information about the definition of a pixel, please consult CSS2.

type script = string 

Script data can be the content of the "script" element and the value of intrinsic event attributes. User agents must not evaluate script data as HTML markup but instead must pass it on as data to a script engine.

The case-sensitivity of script data depends on the scripting language.

Please note that script data that is element content may not contain character references, but script data that is the value of an attribute may contain them.

type shape = string 

The shape of a region.

type text = string 

Arbitrary textual data, likely meant to be human-readable.

type uri = string 

A Uniform Resource Identifier, as per RFC2396.

type uris = uri 

A space-separated list of Uniform Resource Identifiers, as per RFC2396.

Common Attributes

type 'a attrib 
type 'a attribs 

'a is known as a phantom type. The implementation is actually monomorphic (the different element types are distinguished by a homogeneous variable, such as their textual representation) and the type variable `a is just used by the type checker.

NB: It might be possible to use polymorphic variants directly, without phantom types, but the implementation is likely to be more involved.

Core

type core = [ `Class | `Id | `Title ] 
val a_class : nmtokens -> [> `Class ] attrib

This attribute assigns a class name or set of class names to an element. Any number of elements may be assigned the same class name or names.

val a_id : id -> [> `Id ] attrib

This attribute assigns a name to an element. This name must be unique in a document.

val a_title : cdata -> [> `Title ] attrib

This attribute offers advisory information about the element for which it is set.

Values of the title attribute may be rendered by user agents in a variety of ways. For instance, visual browsers frequently display the title as a tool tip (a short message that appears when the pointing device pauses over an object). Audio user agents may speak the title information in a similar context.

The title attribute has an additional role when used with the link element to designate an external style sheet. Please consult the section on links and style sheets for details.

I18N

type i18n = [ `XML_lang ] 
val a_xml_lang : nmtoken -> [> `XML_lang ] attrib

Style

The Style collection is deprecated, because the Style Attribute Module is deprecated.

type common = [ `Class | `Id | `Title | `XML_lang ]

val a_charset : charset -> [> `Charset ] attrib

This attribute specifies the character encoding of the resource designated by the link. Please consult the section on character encodings for more details.

val a_href : uri -> [> `Href ] attrib

This attribute specifies the location of a Web resource, thus defining a link between the current element (the source anchor) and the destination anchor defined by this attribute.

val a_hreflang : languagecode -> [> `Hreflang ] attrib

This attribute specifies the base language of the resource designated by href and may only be used when href is specified.

val a_rel : linktypes -> [> `Rel ] attrib

This attribute describes the relationship from the current document to the anchor specified by the href attribute. The value of this attribute is a space-separated list of link types.

val a_rev : linktypes -> [> `Rev ] attrib

This attribute is used to describe a reverse link from the anchor specified by the href attribute to the current document. The value of this attribute is a space-separated list of link types.

val a_tabindex : number -> [> `Tabindex ] attrib

This attribute specifies the position of the current element in the tabbing order for the current document. This value must be a number between 0 and 32767. User agents should ignore leading zeros.

val a_type : contenttype -> [> `Type ] attrib

This attribute gives an advisory hint as to the content type of the content available at the link target address. It allows user agents to opt to use a fallback mechanism rather than fetch the content if they are advised that they will get content in a content type they do not support.Authors who use this attribute take responsibility to manage the risk that it may become inconsistent with the content available at the link target address.

Output

?encode maps strings to HTML and must encode the unsafe characters '<', '>', '"', '&' and the control characters 0-8, 11-12, 14-31, 127 to HTML entities. XML.encode_unsafe is the default for ?encode in output and pretty_print below. Other implementations are provided by the module Netencoding in the OcamlNet library, e.g.: let encode = Netencoding.Html.encode ~in_enc:`Enc_iso88591 ~out_enc:`Enc_usascii (), Where national characters are replaced by HTML entities. The user is of course free to write her own implementation.

~encoding is the official name of the external character set encoding that is used by outs : string -> unit.

val output : ?encode:(string -> string) ->
?encoding:string -> (string -> unit) -> html -> unit
val pretty_print : ?width:int ->
?encode:(string -> string) ->
?encoding:string -> (string -> unit) -> html -> unit

Tools

val version : string
val standard : uri
val validator : uri
val validator_icon : unit -> [> `A ] elt

A hyperlink to the W3C validator, including the logo.

val addto_class : string -> 'a elt -> 'a elt

Add the element and all its subelements to a class. Note that this is only almost typesafe, because a few elements from the structure class do not support the class attribute. On the other hand, listing all allowed elements would be too tedious right now.

val addto_class1 : string -> 'a elt -> 'a elt

Add the element to a class.

val set_rowspan : int -> ([< `Td | `Th ] as 'a) elt -> 'a elt

Set the rowspan attribute for the element.

val rewrite_hrefs : (string -> string) -> 'a elt -> 'a elt
val all_hrefs : 'a elt -> uri list
val all_anchors : 'a elt -> id list
