lexicon-last-token-path := "TOKENS.+LAST".
;;
;; furthermore, for the various input formats, we need to declare how parts of
;; input descriptions correspond to the grammar-internal feature geometry; in
;; the YY input format, for example, token feature structures (aka input items
;; PET-internally) are created from various parts of the token description.
;;

token-from-path     := "+FROM".       ; [optional] surface start position
token-to-path       := "+TO".         ; [optional] surface end position
token-postags-path  := "+TNT.+TAGS".  ; [optional] list of POS tags
