That's very good news! Very recently I visited
http://www.ldraw.org/Downloads-req-viewdownload-cid-11.html and there it reads:
"Version: 1.3 | File size: 78.00 Kb" and links to
http://www.hassings.dk/l3/l3p.html where it reads: "NEW Read about the v1.3
20010120 release NEW". Maybe time to update some pages?
I haven't checked out how LDView does command line based batch jobs and if I am
able to change LDA to call on LDView to convert the frames into POV instead of
L3P. So I'm not ready to throw out L3P yet. And to abandon L3Lab after all these
years, well I'll do that only if I'm forced to. It's still my LDraw viewer of
choise.

I don't see the point in disregarding backwards compability when there's nothing
to gain with it. I was pro skipping subfiling silver, gold and other special
colored pattern details - but that did only affect original LDraw because of a
tiny bug in it. We still have a couple of hundred color numbers that do not
cause problems with older LDraw programs and utilities that don't search
LDConfig.ldr, why on earth not use them first?
Correct, LDraw.org Colour Definition Language Extension specs doesn't talk about
a forbidden zone. But OTOH, has there been a decision that it's ok to use these
incompatible color numbers?
