Hi all,

I use OCL constraints and I have a problem using Collections:
This expression

let res : OrderedSet(MyConcept) = OrderedSet{} in ...

throws an error. Is the syntax wrong or the EMF OCL implementation that
does'nt support this kind of declaration ?

Cheers.

I forgot to precise the message error:

Unknown type (MyConcept)

It's best to ask on the OCL newsgroup, which I've added to the "to" list
of the reply, so no need to repost.
