Antonio's fix for issue #24.

"Extract information to know which group is producing the spec."
I see two problems here:
* You should probably use `.text()`, otherwise you might XSS yourself (or show some ugly tags)
* There will be cases where you have multiple candidates (some drafts are produced jointly by multiple groups). You probably want to return a list of matches.

In fact it would be nice if at some point we could check joint publications properly (but that requires changes elsewhere too).
