This is now in HEAD. I haven't yet caught all the cases in get_ssa or 
get_mra that drop the info when validation fails, but otherwise it's 
usable. Instead of using the distinct SLAPD_FILTER_COMPUTED type for 
filter components with unknown attributes, it now ORs the 
SLAPD_FILTER_UNDEFINED flag onto the existing filter choice. This way 
the original filter structure can be preserved.

This is now in HEAD as well.
