[mapserver-users] Forcing WMS errors in XML-format in PHP-MapScript

[Jan Hartmann]

This is probably something I should try to look up myself, but perhaps 
someone on this list has a quick answer.

  I'm generating WMS output completely from  PHP MapScript (essentially 
to make non-projected raster files available for WMS clients under a 
fake projection number, to georeference raw coordinates). If something 
goes wrong with the getCapabilities request, I would like to output a 
valid XML error string that can be understood by regular WMS clients. 
Any pointers to documentation on the required/optional XML formats?
