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

[John Schattel]

Hello,

I'm developing a WFS and am planning to require the client to provide 
additional input information (see example below) with its GetFeature 
request.  Is this acceptable for a WFS implementation?

http://host/GMLgen/server/ndfdGMLserver.php?SERVICE=WFS&REQUEST=GetFeature&VERSION=1.1.0&lat=38.99&lon=-77.99&time=2006-10-30T00%3A00%3A00&elements=maxt&TYPENAME=gmlSimpleFeatureType&

Would this additional input requirement be specified in the 
<ows:AccessConstraints> element of the GetCapabilities document or is 
there a better way?

Thanks.

John
