Thanks, Stephan. Unless I'm mistaken, UDX only allows for types on the
preterminals (i.e. lexical types), where the LOGON restful server puts
types on the nonterminal nodes as well. On the other hand, the lexical
types are probably more interesting than the rule types, so even getting
UDX from ACE would be a nice step. Also, pyDelphin has had support for UDX
for a while now, so it is ready to accommodate.

Woodley's recent changes are for an alternative stdout protocol and, I
suspect, not the [incr tsdb()] profiles written by the art utility, so I
don't think the profiles are being made more bulky.
