This is the XML Schema module of named XHTML 1.0 content models
for XHTML-IM, an XHTML 1.0 Integration Set for use in exchanging
marked-up instant messages between entities that conform to
the Extensible Messaging and Presence Protocol (XMPP). This
Integration Set includes a subset of the modules defined for
XHTML 1.0 but does not redefine any existing modules, nor
does it define any new modules. Specifically, it includes the
following modules only:
- Structure
- Text
- Hypertext
- List
- Image
- Style Attribute
Therefore XHTML-IM uses the following content models:
Block.mix; Block-like elements, e.g., paragraphs
Flow.mix; Any block or inline elements
Inline.mix; Character-level elements
InlineNoAnchor.class; Anchor element
InlinePre.mix; Pre element
XHTML-IM also uses the following Attribute Groups:
Core.extra.attrib
I18n.extra.attrib
Common.extra
Full documentation of this Integration Set is contained in
"XEP-0071: XHTML-IM", a specification published by the
XMPP Standards Foundation.
