# This filter removes all strings containing derivational tags
# as defined below. See sme-lex.txt for further documentation.
#
# It should be applied on top of the nonrec transducer.

# A line was added disallowing actio of passives.
# Further, we check that we don't have double passives.
# Then we remove Rel-Foc combinations (could this have been written Foc/*?)
