Henry, A while back you said (see below) that you had some form of canonicalization as part of XSV. Is this accessible for use? If not, do you (or anyone else) know of any tools that will read an XML Schema file and generate a canonical version of it? By 'canonical' I mean that all references to purely structural items are replaced with the actual items. Two schemas that produce exactly the same validation should be equal in their canonical form.
