Hello, I don't recall this particular use of subsetting being mentioned before in this context. XMPP dissalows PIs, commnents, and both internal and external TD subsets. Also, curiously, *pre*defined entities. Which is very weird. XMPP Core draft-ietf-xmpp-core-06 http://www.jabber.org/ietf/draft-ietf-xmpp-core-06.html Abstract This document describes the core features of the Extensible Messaging and Presence Protocol (XMPP), a protocol for streaming XML in near-real-time that is used mainly for the purpose of instant messaging (IM) and presence by the servers, clients, and other applications that comprise the Jabber network. 4.2 Restrictions XML streams are used to transport a subset of XML. Specifically, XML streams SHOULD NOT contain processing instructions, predefined entities (as defined in Section 4.6 of the XML specification[1]), comments, or DTDs. Any such XML data SHOULD be ignored by a compliant implementation. Now, if it was SHOULD NOT contain and compliant implementations MUST ignore then we would have a conformance profile. -- Chris mailto:chris@w3.org
