I would vote now to leave SourceProperty as it is (except fixing
the setValue(String value) method) and cleanup
WebDAVSource.getSourceProperty/ies() with (something like):

    return new SourceProperty(prop.getElement());

InspectableSource implementations without XMLized properties would
have to serialize the XML themselves (in a way they want it to be).
Actually that is what you would have to do then in
WebDAVSource.setSourceProperty() (serializing the XML) since the
WebDAVResource class (of the slide lib) only supports setting
properties via Strings (it's a bit inconsistent in this regard).

But that way you can easily switch SPWT from startTextRecording() to

WebDAVSource.getSourceProperty() also needs to be changed to request
only the wanted property from the WebDAV server and not all

Another thing we have to agree on is the namespace of SPWT which
currently is:

and of course the name of SourcepropsWritingTransformer itself :-)
