• fix namespace problem for georss (and use xpath)

AWESOME!

Two requests before I merge this in:

1. Can you merge in upstream so that there are no merge conflicts?
2. Repeating myself from just-posted comments on pull-request Better all-round 3D support #53:

Can we not deal with these issues of changing the method-inheritance system in this pull-request? (ie, x() and y() methods). It's a valid complaint, but let's keep to the existing pattern (with all it warts) for this pull, and deal with how we do method inheritance in a separate issue, so we can deal with it in a complete way for all methods at once. See comments on #53.

i have merging the change, i think it's ok.
i have not very well tested, the test seems to stucked in a infinite loop... distance calculation take a while ?

i have put methods x() y() etc... to geometry, but non abstract. this make no change.

Thanks! I'm going to do a little bit of clean-up on this. I also want to do some performance testing and tweaking on the WKB adapter before merging into master.

Great, i now work on a Gml adapters.
also i have started to refactor the class for getting out all unnecessary abstract methods.
