Which links weren't you able to access? The configuration files are at 
https://www.seegrid.csiro.au/subversion/GeoSciML/cgi-reference-dataset/tags/2013-02-20/services/geoserver/postgis/data/
 which works for me so I don't know if the site was temporarily down. If you 
mean the links to our service, do you have non-standard ports like 8082 
blocked? I've proxied my service through port 80 so, if that was the problem, 
you should be able to use http://ogcdev.bgs.ac.uk/geoserver-2.3.x-2013-02-14/ 
without the 8082 port number to test now. As it is a development server it can 
be slow / temporarily not running at times so I've made some temporary pastebin 
links to output below.

The equivalent WFS/FES 1.1.0 filters as below give the same results:

IGN/camptocamp have done more work on this in their own repository. Last time I 
tested that the responses were better (although still with some problems) so it 
may be worth looking at merging in some of their changes.
