angela commented on JCR-1261:
-----------------------------
i run into problems with an older version of the pull-parser a couple of month
ago (see Issue #JCR-984 for a description of the problem) and i would want to
be sure, that we don't introduce bugs by changing the xml library.
did you perform test (e.g. litmus)? or do you know whether they fixed these
kind of problems?
> Replace Xerces/JAXP based (un)marshalling by XPP3 based implementation

> Proposing to replace the current Xerces/JAXP based implementation of XML data
> unmarshalling and marshalling to be replaced by a MXP ([1]) based
> implementation. MXP is an implementation of the XML PullParser API [2] and
> provides a very mall footprint (120KB) and far better performance than Xerces
> (my tests showed around 50% performance increase over Xerces for both
> unmarshalling and marshalling, see also [3]).
> Why do I care ? I would like to include WebDAV functionality into Sling and
> bundle is with as little dependencies as possible ( the xpp3 lib might even
> be bundled into this project to minimize dependencies). In addition, I think
> XML (un)marshalling performance is crucial in any WebDAV solution. For this
> reason, this project can only win if we add a more performing library.
