For 2.2 I suggest that what we recommend should be the default. However,
it should clearly be documented how to reconfigure to match 2.1. As far
as which one to choose, I would look at:
1. Compatible license
2. Documentation
3. Performance
4. Ease of integration. (i.e. doesn't have to be ripped from some other
jar, doesn't have a lot of dependencies we don't already have, etc.)

Thanks to Grzegorz efforts, we are now close to be able to use the
same exprssion language and object model both in the sitemap and in
templates.
The whole thing is plugable, so those who have large investments in
the current syntax and models can continue using them.
But while flexibillity is good for back compability it is confusing
for new users. So we should try hard to decide what should be the
default expression language and expression syntax.
Once I preffered JXPath as my webapps where XML-centric and I used
XSLT and XPath everywhere. But now my webapps is more Java based, so
JEXL or JS seem more natural. Of these I prefer JEXL as JS is a little
bit to powerful as an EL for my taste.
But is the rest of world really using JEXL, JS or JXPath as ELs?
Wouldn't it be a better idea to use the Unified Expression Language
(EL) of JSP 2.1 (JSR-245)
(http://en.wikipedia.org/wiki/Unified_Expression_Language). To me it
seem like a rather good EL and there are several Apache licenced
implementations, Tomcat has one and there is another one called JUEL
http://juel.sourceforge.net/.
WDYT?
