Example 1 with ICrossEReferenceAndEObject

the class LinkingXpectMethod method linkedPathname.

 * qualified name again instead of using the qualified name provider, as the latter may not create a valid name for
 * non-globally available elements.
 * <p>
 * The qualified name created by retrieving all "name" properties of the target and its containers, using '/' as
 * separator.
