XAG 4 and Extreme


4.1 Ensure human-readable documentation conforms to WCAG double A
Fail - DTD is too complex for many people. DTD + CSS/XSLT?
4.2 Provide a machine-understandable means/mechanism to get from a document instance to the schema
Pass: Doctype declaration
4.3 Provide explicit human readable definitions for markup semantics
Pass - the DTD does say this
4.4 Use a schema language that can support explicit human-readable documentation or annotation of semantics
Fail. DTD doesn't point to the semantics on a per-element basis
