I just downloaded antlr 2.7.0.  The .zip is 1.3M, but antlr.jar itself
is only 61K.  What were you looking at?  At 61K, antlr is a reasonable
JAR to include.

OK, good reasons.  :-)  Sounds to me like it would be in everyone's best
interests (yours and JDOM's, for reasons laid out in the previous email)
for the JDOM project to host the parser in jdom-contrib, probably
org.jdom.contrib.xpath unless people suspect we'll have competing xpath
implementations, in which case we need something like
org.jdom.contrib.xpath.werken.
