I was going over the topology.AsGML family of overrides too 
as per ticket #955 and noticed that an override might give you
the option of switching between VOLATILE and STABLE.

Not sure it really buys you something but when AsGML is passed
a NULL value for the "visited" table then you can say the function
will be STABLE (only read the db, never write it), while a non-NULL
value will make it be VOLATILE.
