Assuming that the following well formed XML instance reference
and signature validates, is the following example a valid
Signature? (It violates the specified content model).
I'm slightly confusing the syntactical violation with a clear violation
of semantics ("disclaimer") just to show why this might be important,
but [x01-03] could be any name space qualified and wellformed XML.
