For interest, you can do all of this within an attribute in XPath 2.0:
max(for $folder in //folder return count($folder/ancestor::folder))
although possibly the following would be slightly better (depending on
the particular pattern of optimisation in the processor):
max(for $folder in //folder[not(folder)]
return count($folder/ancestor::folder))
