The fact that that the Schema for Schemas can not be used for
validating schemas can be checked here.
(A reply by Xerces Project Lead Gareth Reakes to my mailinglist post
on xerces-user-j on apache.org:
http://blog.parthenoncomputing.com/xerces/archives/2005/04/can_i_validate.html
However, his is not in-line with the original design goals from 1999:
http://www.w3.org/TR/NOTE-xml-schema-req
"The XML schema language must:...
define a useful XML schema for XML schemas;"
The schema for schemas may be found here:
http://www.w3.org/2001/XMLSchema.xsd
Maybe somebody can tell me what its use is if we can not use it in validation??
