edge annotation in frequency analysis

[otichy]

It would be great if edge annotation (func values) could be used in frequency analysis.
Say I search for all tokens "you" that are PROnouns and are dependent on Noun Phrase, which in turn is dependent on an IP and is its SUBJect.

cat="IP" & cat="NP" & "you" & pos="PRO"
& #3 = #4
& #1 >[func="SBJ"] #2
& #2 > #4

Essentially, I am looking for the use of the pronoun "you" as a subject.

Now I would like to be able to perform an analysis of all possible functions/edge annotations of the #1 > #2 dependency (subjects, objects etc).

(the same applies for export, I was not able to export edge annotation with any of the exporters, but maybe I am doing it wrong)
