WFS 1.1 should support advertising multiple SRS

[assefa]

WFS 1.1.0 has the ability to advertise multiple SRS using the OtherSRS parameter in the capabilities.

I have missed adding this although It was specified in the specs and identified as a TODO in the code. Should have added a bug on it.

Here would be the logic to support multiple SRS in wfs 1.1: for each layer

• check the wfs/ows metedata at the map level. If available advertise it as the default srs. if it is a list expose the first one as default srs and the rest as OtherSRS. The map projection is also checked at this point if used the epsg format
• if there is no map level metadata, check the layer level metadata and the layer projection )same logic as above)
• if not display a warning

When a GetFeature? request is done and uses an SRS, It should be valid against all the layers. We already do this validation.

Does this seem correct?
