Captions

Permitted Context: TABLE or FIG
Content Model: %text

The CAPTION element is used to label a table or figure. Use the align attribute to specify the position of the caption relative to the table/figure. For example:

    <CAPTION ALIGN=LEFT>The Niagara Falls</CAPTION>

Should we provide separate align and valign attributes for controlling the horizontal and vertical positioning respectively?

Permitted Attributes

ID
An SGML identifier used as the target for hypertext links or for naming particular elements in associated style sheets. Identifiers are NAME tokens and must be unique within the scope of the current document.
LANG
This is one of the ISO standard language abbreviations, e.g. "en.uk" for the variation of English spoken in the United Kingdom. It can be used by parsers to select language specific choices for quotation marks, ligatures and hypenation rules etc. The language attribute is composed from the two letter language code from ISO 639, optionally followed by a period and a two letter country code from ISO 3166.
CLASS
This a space separated list of SGML NAME tokens and is used to subclass tag names. By convention, the class names are interpreted hierarchically, with the most general class on the left and the most specific on the right, where classes are separated by a period. The CLASS attribute is most commonly used to attach a different style to some element, but it is recommended that where practical class names should be picked on the basis of the element's semantics, as this will permit other uses, such as restricting search through documents by matching on element class names. The conventions for choosing class names are outside the scope of this specification.
ALIGN
Positioning of the caption relative to the table or figure it labels. The permitted values are: TOP, BOTTOM, LEFT or RIGHT.
