I was trying to figure out why certain XML validation operations had gotten slower, so I was digging into Xerces' source when I noticed it didn't have line number attributes. I was directed to the previous discussion at http://markmail.org/thread/qkbaup5dzjrx5ffj which indicates that the decision was made to omit these attributes, in order to reduce jar file size. This makes sense, although it's curious that no other apache projects (such as such as Spring or CXF ) have taken a similar direction, despite having much larger JAR files.
I don't mind checking out and build the debug versions of the Xerces libraries myself, and indeed I've already done so. But maybe for future releases, it would make sense to make these "debug jars" available as separate resources on the download page, for easier access? Or maybe it makes sense to make the "debug jars" as the default ones, and to have the smaller "non debug" jars available as separate resources? Thanks, - Aaron
