Productivity Tools module mount XML APIs (JAXP, DOM, SAX) to classpath.

JDK 1.4 already contains XML APIs so this extra library make sense
just on JDK 1.3 or lower. So, we would like to mount the library just
with Java project JDK < 1.4.

http://www.netbeans.org/download/prj40_prototype/javadoc/JavaSupportAPIs/index.html

We could create XML-APIs library (provided by Java module) that
contains API for compile time, API+impl for run/debug time, API
Javadoc and sources for debug time. [It depends on issue #23798.]

Then it depends on a user if she want to add the library to Resources
and project's classpath.

As described in
http://www.netbeans.org/servlets/ReadMsg?msgId=619519&listName=nbdiscuss the
current work on projects prototype has been stopped.

Well, work on Projects for NB3.6 has been stopped
but for upcomming NB4.0 it's been renovated, right?

thus, even though it's too late for promo-d (4.0), I'm reopening cause
work on Projects still continue and in promo-e PRojects should be mcuh
enhanced.

Any objections?

Probably obsolete; I expect most people to be using JDK 1.4+ at this
point, and those who are not can make their own library.
