COLLADA importer

Ok, now that I’ve gotten the Collada import working, I have another question: How do I put tags in a .dae file so that they’ll import into Panda correctly? I need to be able to create colliders and entities correctly, and I haven’t found any information on how to store tags in a Collada file.

Also, if anyone knows how to populate that data from Blender 2.5, that would also be helpful to know… that’s becoming our model/level toolchain.
