(** XHTML types with variants. (See also {!Xhtml.M}) *)

(** 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:
    {ul
      {- {e elements} are implemented as O'Caml constructors with the same name as
         in the W3C recommendation.  The domain and codomain are specified as ['a elt],
         where ['a] is a concrete phantom type build out of polymorphic variants.}
      {- {e attributes} are implemented as O'Caml constructors with [a_] prefixed to the
         name.  The name is the same as in the W3C recommendation, unless an additional
         prefix is required to disambiguate:
         {ul
           {- [a_fs_rows] and [a_fs_cols] instead of [a_rows] and [a_cols] for framesets,
              because of the different argument types.}}}
      {- {e attribute types} are implemented as O'Caml types that all have the same names
         as in the W3C recommendation, but are all lowercase.}
      {- {e data types} are also implemented as O'Caml types that all have the same names
         as in the W3C recommendation and are again all lowercase.}}

    Finite sets of alternatives are mapped to polymorphic variants.

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

(** 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.

    {ul
      {- [`Alternate]:
         Designates substitute versions for the document in which the link occurs.
         When used together with the hreflang attribute, it implies a translated
         version of the document. When used together with the media attribute,
         it implies a version designed for a different medium (or media).}
      {- [`Stylesheet]:
         Refers to an external style sheet. See the Style Module for details.
         This is used together with the link type ["Alternate"] for user-selectable
         alternate style sheets.}
      {- [`Start]:
         Refers to the first document in a collection of documents.
         This link type tells search engines which document is considered
         by the author to be the starting point of the collection.}
      {- [`Next]:
         Refers to the next document in a linear sequence of documents.
         User agents may choose to pre-load the "next" document, to reduce
         the perceived load time.}
      {- [`Prev]:
         Refers to the previous document in an ordered series of documents.
         Some user agents also support the synonym "Previous".}
      {- [`Contents]:
         Refers to a document serving as a table of contents. Some user
         agents also support the synonym ToC (from "Table of Contents").}
      {- [`Index]:
         Refers to a document providing an index for the current document.}
      {- [`Glossary]:
         Refers to a document providing a glossary of terms that pertain to
         the current document.}
      {- [`Copyright]:
         Refers to a copyright statement for the current document.}
      {- [`Chapter]:
         Refers to a document serving as a chapter in a collection of documents.}
      {- [`Section]:
         Refers to a document serving as a section in a collection of documents.}
      {- [`Subsection]:
         Refers to a document serving as a subsection in a collection of documents.}
      {- [`Appendix]:
         Refers to a document serving as an appendix in a collection of documents.}
      {- [`Help]:
         Refers to a document offering help (more information, links to other
         sources information, etc.)}
      {- [`Bookmark]:
         Refers to a bookmark. A bookmark is a link to a key entry point within
         an extended document. The title attribute may be used, for example, to
         label the bookmark. Note that several bookmarks may be defined in each
         document.}
      {- [`Other]:
         refers to any other type (for example [icon] or [shortcut]).

    The following is a list of recognized media descriptors:
    {ul

      {- [`TTY]:
         Intended for media using a fixed-pitch character grid, such as
         teletypes, terminals, or portable devices with limited display
         capabilities.}
      {- [`TV]:

         limited scrollability).}
      {- [`Projection]:
         Intended for projectors.}
      {- [`Handheld]:
         Intended for handheld devices (small screen, monochrome,
         bitmapped graphics, limited bandwidth).}
      {- [`Print]:
         Intended for paged, opaque material and for documents viewed
         on screen in print preview mode.}
      {- [`Braille]:
         Intended for braille tactile feedback devices.}
      {- [`Aural]:
         Intended for speech synthesizers.}
      {- [`All]:
         Suitable for all devices.}}

    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:
    {ol
      {- 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"].}
      {- 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"].}
      {- 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 = [ | length | `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.
