Aside from the fact that only global elements have global scope, what
are the operations that are only achievable on global elements? I've
taken a quick look at the structures recommendation and the primer, and
I have not found a list of these. The primer does mention limitations of
global elements, that they cannot contain references or have cardinality
constraints.
