paradigm in that way, you could write a GME AddOn (event-driven plug-in) whose
execution criteria are the same as those for the OCL constraint you want to
write. Then you can do whatever arbitrarily complex comparisons/manipulations
you need using C++ instead of OCL, and present the user with an error pop-up if
necessary. You can even reuse the code from the GME ConstraintManager (it’s
just another GME Addon itself), since GME is open source.<o:p></o:p></span></font></p>

like to add an OCL constraint that would use the sequence of strings. I doubt
that OCL (either the official version of GME’s version) supports
parsing/iteration of a sequence of strings as you outline below. If it does
please let me know.<o:p></o:p></span></font></p>
