Hi, Peter,
The Copier can copy a collection of EObjects in one operation, which
results in also copying the cross-references between them.
So, if you retrieve the stereotypes instances applied to your element
(using Element::getStereotypeApplications()) and add those to a
collection along with the base element, then copy the lot, you'll get
what you expect.
The only trick, then, is to find a place to store the new stereotype
applications (usually they are attached directly to the resource that
contains the base element).
HTH,
Christian
