CORP — Use of expression as sequence/array bound

According to the IDL 4.2 grammar, the bound number of bounded sequence / bounded string and fixed array size is a
positive_int_const which resolves to const_expr.
In the examples for bounded sequence an array, the specification only shows literal constants used for the sizes.
It is not defined how to use expressions, such as a reference to an IDL const declaration, as the size.
At the least, it should be required to model a UML Dependency association from the CORBASequence / CORBAArray type to the const declaration.
