hey, i told you i don't use python2.2 yet ;)

you mean the classes inside schema.py such os "ObjectClass", "AttributeType"
  etc? i am noticing that the __init__ for ObjectClass, unlike all others, 
does not just take the full schema_element_string, it also takes all 
attributes as separate keyword arguments. that seems a little redundant. 
all other classes only take the schema_element_string and extract the 
attributes from that.

i don't have time to implement it and throw it out right at this moment, 
anyway. i'm fully aware that something so "new" will change more frequently.

well, i would probably end up doing a widget that offers both a dropdown 
and a text input field, maybe depending on errors occurring during schema 
discovery.
