Schema for XHTML

The schema for XHTML published at

http://www.w3.org/TR/2002/NOTE-xhtml1-schema-20020902/

is invalid, because it uses regex patterns that have been outlawed by errata
to the XML Schema specification.

The schema validator in Saxon [1] consequently rejects this schema. This is
a little embarrassing, since one of the main benefits of schema-aware XSLT
processing is to validate that the output of a stylesheet conforms to a
required schema, and for many stylesheets, that schema is XHTML.

Does anyone know if there are plans to publish a corrected XHTML schema? I
can do it easily enough myself, but one would prefer something official.
