Correct.

OK -- what would those be? My ideas were quite similar, but I got stuck try=

to determine an appropriate "default set of provider configuration=20
properties", to be honest...

Hmmm. I was actually thinking about catering for configuration properties t=
hat=20
affect the entire factory and subsequently created providers. Like a=20
SAXParserFactory which you can configure to create namespace-aware and=20
non-namespace-aware, or validating and non-validating parsers. I must admit=
,=20
however, that I can't currently think of any such factory-wide config=20
settings that would make sense for the TopicMapProviderFactory. So this wou=
ld=20
qualify as a nice-but-not-necessary feature. :-)=20

BTW, how is your testing on TopicMapSourceSupport and the modified=20
TopicMapProvider interface coming along? I'd like to add support for=20
TopicMapSource to the TopicMapMerger class (and consequently for the=20
TopicMapMergingTask as well). Could you give me a status update on that?

Thanks in advance,
