Somehow the git-send-email patch didn't make it to the mailing list,
though my reply to it did...I've attached the patch here, hopefully this
one doesn't get flattened.

I decided to allow vendor and product to be set independently of each
other in order to allow greater flexibility at the possible expense of
namespace clashes.

The only change is that these should use virBufferEscapeString
since vendor/product strings might contain<,>  or&  characters
which would make the XML unhappy

Ok, so I've updated that.  Hopefully all is well with this patch!

Best,
