Thanks for the details - I have managed to plug-in an additional binding
type in the meta-model and the diagram too, I did not try out this story
with the validator.
Btw, I cannot access the svn repository for stp. I tried with anonynous
and non=anonymous access but no success, the svn+ssh: says "connection
timeout" and svn: says "no such repository". I had to walk thtough the
sources via the web interface. Do you experience problems with the stp svn
repo these days? or if you have some hint, what could be wrong?
