Re: Disjoint datatypes?

No, sorry, not in version 1.
You cannot create a type out of the union of disjoint types, say, integer
and string.
You also cannot union two separately declared enumerations.

All the best, Ashok

Subject:  Disjoint datatypes?



Can I build a datatype out of pieces that are disjoint? A simple example
might be US_states + Canadian_provinces. Say my schema already contains
declarations of these two enumerations. The new enumeration I want is the
merger of the two. I don't want to extend one with the members of the
other,
explicitly written out.
A more complex case is SQL style datatypes: integer + NULL. Can I build
such
a datatype in XSchema?
Thanks,
David
