proposal for 4.2.1

Based on today's discussion and Greg's stab, here is another proposal
for wording SC 4.2.1:


When [multiple versions of a Web unit] are available, at least one
version conforms at Level A. Any version that does not conform at Level
A  provides a mechanism to obtain a version that does, and that
mechanism meets all Level 1 success criteria.

Glossary entry:
multiple versions of a Web unit:
Web units in the same natural language that provide all of the same
information and functionality <http://www.w3.org/WAI/GL/WCAG20/> 


Is this getting any closer?
