[Community] OWSLib - Access WMS attribution info

[Dominic Lowe]

Hi David,

I'd welcome a patch on this - that would be great.

It's worth noting that we're trying to keep the interfaces harmonized 
across service types as much as possible - however I had a look at WCS 
and WFS to see if there is anything similar and there isn't  - so in 
this case I think it's fine just to extend the WMS content metadata section.

I think it would be more in keeping with the rest of the library if it 
was a dictionary at this level rather than another type of object - as 
you can see here most things at the content metadata level are 
lists/strings/dictionaries etc:
http://trac.gispython.org/lab/browser/OWSLib/trunk/owslib/interfaces.py#L139

Anyway a patch would be welcomed!
Also it would be good to work this into a test somewhere - if you have a 
capabilities XML document that supports this we could use that as a 
basis for testing.

Cheers,
Dominic
