Here is a helper that should remove all empty sequences recursively:
helper def : removeEmptySequences(seq : Sequence(OclAny)) : Sequence(OclAny) =
seq->collect(s | if s.oclIsKindOf(Sequence(OclAny)) then thisModule.removeEmptySequences( s.asSequence() ) else s endif)
->reject( s | if s.oclIsKindOf(Sequence(OclAny)) then s->size() = 0 else false endif );
