Then in a data-centric design, I would concentrate on one schema language, and more particularly, I would concentrate on the instances I wish to produce. Yes? Or what does it mean to say "instances are equal"? In a relational system, it is as if one designed the report data, then designed the tables, then designed the queries that produce the reports. Then they discover the business rules. Then they create the GUI. Naive yes, but I want an explanation I could give to a naive person. If I have to resort to explaining QNames, the explanation is DOA.

Dayadhvam.h -----Original Message----- From: Jonathan Borden [mailto:jborden@m...] In particular statement [3] which defines Schema Equality as Instances(a) = Instances(b), that is two schemata are 'equal' if their instance sets are equal. One schema might use the XML Schema language and another the RELAX schema language, but if the set of instance documents are the same, the two schema are said to be equal. I have not addressed the issue of how one might actually determine that two schemata are functionally equal, but this is the general direction.
