Thanks.

- Just like some media documents, this file is dual licensed
  with GPL and GFDL. As right now the GFDL SPDX definition is
  bogus (as it doesn't tell anything about invariant parts),
  let's not use SPDX here. Let's use, instead, the same test
  as we have on media.  

The dual-licensing really can't be expressed with an SPDX tag?  Because...

A SPDX dual license should be possible, as it's used for GPL and BSD in
several locations.

...adding all that boilerplate is kind of a bummer.

At a minimum I'd want an ack from Steve (who wasn't copied) before
applying this, but it would be better to add a bit more SPDX
infrastructure to express this if possible.

Thanks,
