please help a newbie I am so confused by trying to declare a user type, and
then incorporate it into an element that uses the derived type and has an
attribute.
I have included my schema and xml file below. I am using xml spy and the
message I get is Phone must be valid with respect to definition '{no name}'.
Thanks for any help at all.
