Sorry, we don't have that.

You might try taking the mtn:execute entry out of the 
attr_init_functions table (and clearing the attr on existing files), so 
you don't have both attrs populated on the same files. This wouldn't 
work if you're collaborating with people using the standard attr hooks, 
but it's probably the cleanest solution.
