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. http://www.xmpp.org/extensions/xep-0071.html
