* This function returns a Package reference that corresponds to a qualified name.
* Packages are created, if not existing yet - the function is thus a bit similar to
* the unix mkdir -p command. Note that the main model within the list of name-spaces is
* ignored, in order to avoid that a sub-package within a model starts with the name
* of the model.
*
* Caveat: imported elements must be checked beforehand. In case of a package import,
* getMembers (and getImportedMembers) will not return the name of the imported model
* but the elements (directly) owned by the imported model.
* Example: getMember ("BasicTypes") will return null whereas getMember ("CORBA")
* returns a package (CORBA is a package within the model library BasicTypes)
*
* @param model
* a model
* @param list
* a list of namespace elements (as can be obtained via allNamespaces),
* the top-level element is the last within the list.
* @param skipTop
* if true, skip top level namespace element
