Though I don't think this will work with 1.0 deliver since it doesn't
understand namespaces.

IMHO the sieve spec missed a trick in this respect.  Given that there are
many other places in sieve where a list of strings can be supplied as
arguments it seems like it would be obvious that

fileinfo ["foo" "bar"];

could carry the meaning of file into the "bar" subfolder of "foo" and just
short circuit the "what's the hierarchy separator?" question.

Maybe this was considered during the standardization process and rejected.
