Hi Jorge, I've just re-analyzed the situation you've described in right earnest, and following are my findings:
Xerces-J is supposed to use following two branches from Eclipse WTP project located at dev.eclipse.org R3_2_maintenance (this is where the product code of XPath 2.0 processor, is stored which Xerces-J is using. We use this, because this branch as agreed works with JDK 1.4) R3_2_xpath2_14unittests (this is where the unit tests are located, which tests the product code of R3_2_maintenance branch. To run these unit tests, we would need JDK 1.5) These two code branches were created only to facilitate Xerces-J XML Schema 1.1 development. I think these decisions date back to few years ago. I have all the latest code from these two branches, on my development workstation. Following are the results of unit tests run, that I get as of today: There are total 8276 tests on the R3_2_xpath2_14unittests branch. Except for 3 tests in the file CatalogTest.class, that give java.lang.OutOfMemoryError to me, 8273 tests pass. I think these results are great, and there should not be any doubt about the quality of the XPath 2.0 processor, that Xerces-J is currently using on the SVN. The other points that I would like to reply are: You've mentioned a github project, that's forking the XPath 2.0 code base from Eclipse WTP dev.eclipse.org site and making improvements on it. I personally have no issues with this and if you wish to use such an improved PsychoPath XPath 2.0 processor at rackspace. I think, it is convenient for Xerces-J for the next XML Schema 1.1 release, to use the PsychoPath jar which is kept at present on the SVN. But I also think, Xerces-J must have a mechanism to have an improved XPath 2.0 processor anytime in future, than what we currently have on the SVN. I think, the right way for this will be one of the following options: 1) Any improvements must be mentioned as Eclipse WTP bugs on Eclipse forums, and ask for fixes there. We can get new XPath 2.0 jars as part of Eclipse WTP releases. 2) We host a copy of PsychoPath XPath 2.0 code base from R3_2_maintenance and R3_2_xpath2_14unittests branches, as branches on Xerces-J source code site. I think I'll be able to do this, by committing from my development workstation. But for that, I'll need permission from Xerces-J dev members and ideally from PMC also. Someone else may also, fetch latest code base from Eclipse WTP R3_2_maintenance and R3_2_xpath2_14unittests branches, and commit to Xerces-J SVN. 3) We take all new improvements for PsychoPath XPath 2.0 code base, from the github PsychoPath site that you've created for rackspace. But the first two options that I've mentioned, look more natural to me when I see how Xerces-J and Eclipse WTP work together. I'm copying this mail to Michael if he would like to comment anything on this.
