Henry, are you saying that in XML Schemas, a schema-defined attribute
specified by a user in an instance (apart from xsi:type) can ever select
the type or facet of the value of that element or of another
attribute?     

Can you give an example?  (Note, I am not talking about fixed or
defaulted values from a schema documenting the current type. That is
something quite different. I mean keying {i.e. selection} of type.)


Rick.
