Re: XMLSchema.xsd question

Hi Dave,

the schema for schema (XMLSchema.xsd) is not meant to be used for validating
other schemas directly. The definitions contained in the schema for schemas
are built-in into validating parsers.

There was an announcement on this list some week ago of a tool from IBM to
analyze schemas. Maybe you just use that.
