That is a statement about a particular product, not a necessary
statement about the sForS.  The Second Edition of the W3C XML Schema
REC [1] incorporated several long-standing errata [2] with the result
that the sForS is both a schema-valid schema document and the XML
representation of a valid schema.

Note that there is a difference between testing whether any schema
document is schema-valid wrt the sForS, and testing whether it
corresponds to a valid schema per _all_ the rules in the Schema REC.

Most schema processors provide a separate form of invocation to do the
latter, more stringent, test.
