DWITHIN filter question

[Pagurek,Debbie [NCR]]

I would like to find out what polygon (my polygon layer is in EPSG:42304) a given point (provided in latitude/longitude) falls into. 

Is it possible to combine epsg codes like this? 
The example provided on the How To page provides the following example.

http://www2.dmsolutions.ca/cgi-bin/mswfs_filter?&VERSION=1.0.0&SERVICE=WFS&REQUEST=GetFeature&TYPENAME=popplace&Filter=<Filter><DWithin><PropertyName>Geometry</PropertyName><gml:Point><gml:coordinates>2587598.000000,404010.531250</gml:coordinates></gml:Point><Distance units='m'>1000</Distance></DWithin></Filter> 

Is it possible to specify <gml:Point srs=EPSG:4326><gml:coordinates>-75,45</gml:coordinates></gml:Point><Distance units='m'>10</distance>...

Is it srs or srsName?

I tried this and I wasn't able to get it to work - every feature was returned.
