There was a significant change to the editor, allowing the filter to be
automatically updated when items are added to the Schema Map editor.
The driver filter is updated only in the case of a Schema Mapping policy.
Addition of a class and attributes to the Schema Map editor leads to
the addition of classs and attributes to the filter as well. These
classes and attributes which are added to the filter follow the default
settings for all the filter attributes (Publish,Subscribe,Merge
Authority, and Optimize Modifications to the Identity Vault).
Attributes added as non-class specific attributes and class/attribute deletes are not handled at this time.
