I don't have such a set of GML files me neither, but if I was in your 
place, I would grab some interesting shapefile and postgis tables,
configure them into GeoServer 1.6.0 nightly 
(http://geo.openplans.org/nightly/trunk/) and then issue a GetFeature
request that will get you a single feature using a FEATUREID filter.

If you want a single feature in GML3 you can use a WFS 1.1 query:
http://localhost:8080/geoserver/wfs?request=GetFeature&version=1.1.0&typeName=topp:states&FEATUREID=states.3
and to get the same in GML2, use a WFS 1.0 query:
http://localhost:8080/geoserver/wfs?request=GetFeature&version=1.0.0&typeName=topp:states&FEATUREID=states.3

Figuring out the feature id is generally easy. In GeoServer feature ids
are constructed as <typename>.<key> where key is the row number in a
shapefile, or the primary key value in a postgis table.

Hope this helps
Cheers
