Item Number: Conformance claims
Part of Item: 
Comment Type: TE
Comment (Including rationale for any proposed change): While many accessibility criteria can hardly be formalised to be automatically checked by a validator, some of them can.



Previous attempts have been made to formalise some of WCAG 1.0, such as the W3C \"Web Content Accessibility Checking Service\" [http://www.w3.org/2000/07/eval43/] using Schematron [http://www.w3.org/2000/07/eval43/wai.xml] or the more advanced Petr Nalevka\'s \"Relaxed validator\" [http://badame.vse.cz/validator/] using Relax NG with embedded Schematron [http://cvs.sourceforge.net/viewcvs.py/relaxed/relaxed/conf/schema/rng/modules/wcag.rng?view=markup].


Proposed Change: Propose some schemas for checking some of the accessibility rules in (at least) HTML documents (using e.g. XML Schema, Relax NG, Schematron) checking for the criteria that can be formalised. Relax NG + Schematron is imho a good candidate.



Cordially,

Alexandre Alapetite
