A CAML View of a SPList

Want to get some Guid's of a list or some of its site column Guid's while developing features.

http://Foo/Library/_vti_bin/owssvr.dll?Cmd=ExportList&List={DA45FCA4-2B2C-4532-8E89-65FF6813F057}

This will emit the information as CAML/XML there we can find all the information.
