Xtext create nested scopes

My xtext grammar constrains a hierarchical structure. When the scope of an element in the hierarchical needs to be computed the following must be done:

add the two list to the scope. Repeat the for the parent element and add the parents scope to the current scope.

I use 

scope_a =  Scopes.scopeFor(list_a)
scope_b =  Scopes.scopeFor(list_b, scope_a)

but get stuck when adding the parents scope to scope_b to create the final scope.

the scopeFor methods are just helpers. have a look at their code. they call

org.eclipse.xtext.scoping.Scopes.scopeFor(Iterable<? extends T>, Function<T, QualifiedName>, IScope)

which allows to pass a parent scope
