Hi Stefan,
I guess that first and foremost it's about what works--and if there are
non-edgecase situations where a static method won't do the trick, it won't
make sense to go that way.
There are other reasons for preferring the status quo too: If we moved the
Version class in line with this proposed standard (which never did get much
support, IIRC), then it becomes difficult for people to tell which Xerces
comes first on their classpaths if two happen to be there and they have
different Version conventions.
So we're probably stuck for the time being...
Cheers,
Neil

OK,
but what about (from the Xalan javadoc api org.apache.xalan.Version):
'This class implements the --> upcoming standard of having
org.apache.project-name.Version.getVersion() be a standard way to get
version information <-- ???? . '
What will be the standard ? A static or non-static class ?
I prefer the non-static method (much more easy to call).
Stefan
