How to GetFeature with srsCode?

I'm forming a GET request like this:

http://usalvwdgis1/mapserver2013/mapagent/mapagent.fcgi?SERVICE=WFS&REQUEST=GetFeature&VERSION=1.1.0...

 

And get a response like this:

<!-- Feature 2 -->
<gml:featureMember>
  <Water:WA_LARGE_VALVE>
    <Water:FID>78935</Water:FID>
    <Water:Geometry>
      <gml:Point>
        <gml:pos>498289.041000 5459452.306000</gml:pos>
      </gml:Point>
    </Water:Geometry>
  </Water:WA_LARGE_VALVE>
</gml:featureMember>

 

 

The pos is in the coordinate system of the underlying data (EPSG:26910) and not the WFS default (EPSG:3857).  When I add an SRSCODE to the query string the result is unchanged:

 

http://usalvwdgis1/mapserver2013/mapagent/mapagent.fcgi?SERVICE=WFS&REQUEST=GetFeature&VERSION=1.1.0&MAXFEATURES=2&TYPENAME=Water:WA_LARGE_VALVE&srsName=EPSG:26910

 

http://usalvwdgis1/mapserver2013/mapagent/mapagent.fcgi?SERVICE=WFS&REQUEST=GetFeature&VERSION=1.1.0&MAXFEATURES=2&TYPENAME=Water:WA_LARGE_VALVE&SRSNAME=EPSG:4326

 

Yet if I provide an SRSNAME that is not registered with the WFS service I get an error (as expected):

The coordinate system conversion failed. Could not create the coordinate system from WKT: EPSG:900913

 

I've read through http://wikihelp.autodesk.com/Infr._Map_Server/enu/2013/Help/0002-Studio_U0/0064-Working_64/0076-Publ... and appear to have followed the instructions carefully.  To confirm I checked the WFS getCapabilities...the SRS data is just as I expected:

 

<wfs:FeatureType xmlns:Water="Library://QA/Data/Water.FeatureSource">
  <wfs:Name>Water:WA_LARGE_VALVE</wfs:Name>
  <wfs:Title>Water</wfs:Title>
  <wfs:Abstract/>
  <wfs:DefaultSRS>EPSG:3857</wfs:DefaultSRS>
  <wfs:OtherSRS>EPSG:4326</wfs:OtherSRS>
  <wfs:OtherSRS>EPSG:26910</wfs:OtherSRS>

 

 

Can someone please explain what I can do to get this to behave as expected?

How would I overlay a WMS layer with public tiles (OSM, Google, Bing, etc.)?
