In SAXON 6, I had to switch between tiny tree and normal tree models
to get performance close to XT for various stylesheets (which was
still almost twice faster -- in one particular but rather important
case).

My impression is that restrictions imposed by RTF could be used to
implement RTF generation more efficiently than node-sets.

Since many stylesheets just generate result tree in one pass and
do not convert them into node-sets (in XSLT 1.0), a good implementation
could implement RTF in a much more efficent way than node-set.
