PropertyHandle :: CanUpdateCollection - Can collection be updated

The function returns whether the collection can be updated, i.e. whether instances can be added, renamed or removed or deleted from the collection ( true ) or not ( false ).

Returning true implies that collection is accessible ( CanAccess() ). There are several reasons for denying collection update:

1. The property handle is opened for read, only
2. The current application does not have rights for updating the collection (disabled by context)
3. The property handle is invalid.
