I have never heard of this and cannot find a reference to it in the WMS 1.1.1 spec at <a href="http://www.opengeospatial.org/standards/wms,">http://www.opengeospatial.org/standards/wms,</a> nor in the new 1.3 spec (not supported by MapServer). The WMS spec does not say anything about the internal details of an SRS definition, so there would be no way to know what to find inside a URL-based reference to a file defining an SRS.<BR>
<BR>
It is very difficult to compare SRS definitions when described parametrically; there are several ways of saying the same thing, and it’s hard to tell whether minor differences are supposed to be differences or just discrepancies. That’s why the use of SRS catalogs is so helpful – the model of namespace:srsname makes it easy to tell whether a requested SRS is something you can understand or not.<BR>

Hi,<BR>
it is misunderstanding, I mean this style of SRS parameter value: "<a href="http://my.server.com/path_to_file_with_mySRS_definition">http://my.server.com/path_to_file_with_mySRS_definition</a>" <a href="http://my.server.com/path_to_file_with_mySRS_definition"><http://my.server.com/path_to_file_with_mySRS_definition></a> <BR>

It does, specify SRS=EPSG:4326 (or whatever SRS you like) in the URL and<BR>
make sure the EPSG code is advertised in the map file's METADATA section<BR>
under the "wms_srs" entry.<BR>

Hi,<BR>
<BR>
I think WMS spec gives a chance to define SRS by public URL <BR>
of file with <BR>
definition of SRS. I don't know if MapServer supports this.<BR>
