It's just stripping the namespace prefixes for back compatibility, that's the way the system originally worked way back in LPS v 1. There is an attribute of dataset called "nsprefix" which can be set to true to preserve namespace prefixes. I would like to set it to true by default, but have held off doing that just because there never seemed a good time to do it. But I'd be all for changing the default.
