Yeah, I figured that one out. the thing I dont see is how I set this up to work
recursively (until the quota attribute is found). What I need is something
similar to postfix "special_result_attribute" and "leaf_result_attribute"
options (with the exception that I need to select one/closest of the
attributes found, whereas postfix gets them all)
