The latest draft for the XSC:Doc and XSC:More elements follows, updated for namespaces. Because these elements may (or must, in the case of XSC:Doc) contain elements that use other namespaces, the rules are slightly different. As always, a prettier HTML version of this will be posted shortly at http://purl.oclc.org/NET/xschema. Simon St.Laurent Dynamic HTML: A Primer / XML: A Primer / Cookies 2.6 XSchema Extensions XSchema provides areas in which XSchema developers can provide supplemental information and metadata regarding XSchema components in both human- and machine-readable formats. Human-readable information is provided through the use of a subset of HTML that conforms to XML syntax, while machine-readable information may be provided through the XSC:More element. 2.6.1 Documentation Extensions Human-readable documentation for XSchemas should be provided using the Itsy Bitsy Teeny Weeny Simple Hypertext (IBTWSH) format created by John Cowan. The full DTD is available at http://www.ccil.org/~cowan/XML/ibtwsh.dtd. Documentation that uses portions of the IBTWSH format may be included in the XSC:Doc element, a subelement available to all declarations. The XSC:Doc element provides basic formatting options for XSchema documentation. <!ENTITY % ibtwsh SYSTEM "http://www.ccil.org/~cowan/XML/ibtwsh.dtd"> %ibtwsh; <!ELEMENT XSC:Doc %horiz.model;> <!ATTLIST XSC:Doc xmlns CDATA #FIXED ""> Note that because XSC:Doc redefines the default namespace to support IBTWSH, the XSC: prefix must be used for XSC:Doc. Any element allowed in the IBTWSH horiz.model set of elements (A, BR, SPAN, XML, CITE, CODE, DFN, EM, KBD, SAMP, STRONG, VAR, or parsed character data) may be used in the XSC:Doc element. Note that IBTWSH does not use namespaces in order to preserve compatibility with HTML. XSchema applications should ignore all XSchema declarations (i.e., elements prefixed with XSC: or another appropriate XSchema prefix) within an XSC:Doc element. (The XML element of IBTWSH allows an ANY content model.) 2.6.2 Other Extensions The XSC:More element provides an area which developers can use to create their own supplements to XSchema, defining content types more tightly than is possible through XSchema 1.0. The XSC: More element has a simple ANY content model, though XSchema processors should ignore the appearance of any elements from the XSchema namespace in this area. <!ELEMENT XSC:More ANY> <!ATTLIST XSC:More xmlns CDATA ""> Because XSC:More redefines the default namespace, the XSC: prefix must be used for XSC:More. Developers may override the blank value of the xmlns attribute to define their own default namespace for elements contained in the XSC:More element. xml-dev: A list for W3C XML Developers.
