[wfs-dev] Extra Key/value Pairs on a GetFeature

[Panagiotis (Peter) A. Vretanos]

John,

Yes this is acceptable as long as the request is still valid if the 
additional parameters are ignored.  If I remove the non-standard 
parameters from your request I am left with:

http://...some_server.../wfs.php?SERVICE=WFS&REQUEST=GetFeature&VERSION=1.1.0&TYPENAME=gmlSimpleFeatureType

which is a perfectly valid request that any WFS could process (although 
you would likely get a exception about 'gmlSimpleFeatureType' not existing).

You would advertise the additional capabilities using the 
"ows:ExtendedCapabilities" element.

Ciao.
