The consensus from the teleconference is that a type should be considered 
derived by restriction from itself and that a type should not be considered 
derived by restriction if every member of a union type is a restriction of the 
specified type.

typeinfoisderivedfrom01:  Checks that a DTD type will return true for 
restriction if the namespace is the XML URI and the name matches the DTD type 
name.  Previously DTD types always returned false for isDerived.

typeinfoisderivedfrom02, 14, 28:

These tests used to check that a schema type was not considered derived from 
itself.  The tests have been changes so that a type is considered derived from 
itself by restriction but not any other method.

typeinfoisderivedfrom18:

This test checked if a union type where every member type was derived from 
xsd:ID considered itself derived from ID by restriction.  Previously expected 
true, now false.

typeinfoisderivedfrom64:

This test was submitted in last nights submission from IBM and was not 
consistent with the previous tests.  This test checked if the type of an 
attribute considered itself derived from itself.  It was rewritten so it 
passed the previous impl and back to close to its original form (plus an extra 
assertion).

typeinfoisderivedfrom65:

The previous test expected the type for the sub element to be a list of 
strings which it is not.  Changed the element name to "strong" which is a list 
of strings.
