Here are two alternative approaches:

1) Sc34 puts in a request to get IS8601 altered to define this case. Also
request W3C XSD WG to define this case

2) Use the XSD date but define the treatment of dates such as 2000-02-31
as a matter of error recovery. The document with this would not be a
conforming Strict document, and a consumer application may decide to fail
and should report it. I probably favour this approach.

Thinking more in terms of standard error recovery strategies would a
useful tool in our toolbelt. This is how the WhatWG are treating HTML for
example.
