[Community] New OWSLib interfaces test

[Dominic Lowe]

Hi all,

I have just added a new test to OWSLib to check that all service types 
(WMS/WCS/WFS/CSW) comply with the OWSLib OWSCommonesque service definitions.

the test is here:
http://trac.gispython.org/lab/browser/OWSLib/trunk/tests/ows_interfaces.txt

and the interface definitions here:
http://trac.gispython.org/lab/browser/OWSLib/trunk/owslib/interfaces.py

You can run this test from the tests directory using:
	python runalldoctests.py -t ows_interfaces.txt 

It doesn't pass yet - but it's close! There are some issues with the way 
contents is implemented in CSW - it uses a list, the others use a dictionary. 
The WCS also has a couple of attribute issues I need to look at.

We may also want to consider if the interfaces are still correct - 
IContentMetadata particularly seems a bit WMS specific now (e.g. has 
a 'styles' attribute). 

Also I am sure this cross-service test could be expanded greatly - feel free 
to improve upon what's there.

Cheers
Dom


p.s. Just realised I've completely missed off SOS  -  not sure where this is 
up to? Is it working? I couldn't see any tests for it.
