[jdom-interest] Small but irritating problem

[Per Norrman]

Hi,

exactly this behaviour was noted two days ago here:
    http://jdom.org/pipermail/jdom-interest/2004-October/014283.html

As I said in reply, I'm not sure why this happens. Xalan and saxon
gives different results. Maybe its due to SAXOutputter
firing a startPrefixMapping even if the first namespace is the
empty unprefixed namespace--at least I think it does that looking
at the code. The behaviour changed for you, maybe it's due a newer
xalan release?

Wait, wasn't there a dicussion of this some half a year ago ......

(intermission)

Yes there was. The code is changed in SAXOutputter. In b9 and before it never
reported mappings for the empty namespace.
