Have some metamodel MM1 with package having NS URI ending with "#", and another metamodel MM2, that uses MM1.

When using this MMs with CDO, I had problems with resolving MM1 package elements by URI, so I think problem is "#" symbol, looks like it's being truncated in some places, and not truncated in other.

In CDO we decided to use the hash character to separate package nsURI from classifier name when we use a single string to unambiguously identify EClassifiers in the scope of a package registry. I thought that was a good decision because the hash character is reserved as a fragment separator in XML anyway.
