On the @ident of <constraintSpec>

[sydb]

This ticket is part of the solution to Stylesheets ticket 541.

1. All of the @idents of all <constraintSpec>s in the Guidelines should be unique.
2. Part of the build testing process should check for said uniqueness.
3. A <constraintSpec> should be added to warn users if a duplicate constraintSpec/@ident is created (i.e. with @mode of "add"); this could be used to satisfy (2), above.

I made this HIGH priority because it blocks further progress on the Stylesheets issue.

The only reason I can imagine for multiple constraintSpecs with the same ident is if they're simply different language versions of the same constraint, and would need to be processed in the same way (deletion or replacement or whatever) when the same ODD is built in different languages. But there are other ways to achieve that, I guess.
