I've just read the XSchema spec for the first time and have some minor

 - 2.3.5: Perhaps the reference content model should be called element
          content model instead? That's what it is and the Element GI
          is free since element declarations are called ElementDecl.

          In the very last paragraph there is a typo: OneOrMore should
          be ZeroOrMore.

 - 2.3.6: "The XSchema processor should ignore any frequency attributes
          in the Ref element."

          Perhaps it would be better to require it to give a warning, since 
          quite a few people are bound to try this and will be confused 
          when the content model is silently accepted, but still doesn't 
          work like they expected.

 - 2.4.3: The thorny issue of entity references in attribute default values
          does not seem to be dealt with in any way. Perhaps this should be
          explicitly disallowed, since XSchemas do not provide any means
          for entity declaration? If not, should entity references of the
          standard kind be regarded as parameter entity references in DTDs,
          while &amp;entref;-style references be considered entity
          references in the entity replacement text? In the latter case,
          how would these entities be defined?

          Although the standard interpretations of XML constructs may make
          this a non-issue I think it would be a good idea to spell out the
          XSchema policy on this to avoid confusion.

 - 3.0:   Simple typo in second paragraph:
          "...the 18 May 1998 "Namespaces in XML" Working Draft and is
          will change ..."                                          ^^

Apart from these nits the XSchema spec looks good to me, although more
features would of course be desirable.
