GetStyles returns ServiceException even if response is okay

[tomkralidis]

(using MapServer 4.2b3):

If I issue:

http://localhost/cgi-bin/mapserv.exe?map=c:/ms4w/mymapfile.map&version=1.1.1&service=WMS&request=GetStyles&layers=rivers

I get :

Content-type: application/vnd.ogc.se_xml

Which is defined as an error content-type in OGC:WMS.

However, if I look at the XML response, I expect an ServiceException XML
document, however I get back the SLD document as requested.

Looks like the content-type decl is off?

Looking at mapwms.c, looks like this is a simple change in the msWMSGetStyles
function, where the statement:

printf("Content-type: application/vnd.ogc.se_xml%c%c",10,10);

...should be:

printf("Content-type: text/xml%c%c",10,10);

Can someone commit this?

Actually, according to section 13.1 of the SLD 1.0 spec, the MIME type should be
application/vnd.ogc.sld+xml:
 
" On successful extraction, an SLD document is returned of MIME type
  "application/vnd.ogc.sld+xml". " 

Is this correct, or is there a reason why we should use text/xml instead?

[dmorissette]

I have committed a fix in 4.3 and 4.2.x (to be released in 4.2.3) to use MIME
type application/vnd.ogc.sld+xml for the GetStyles response.

Oh, ok.  I didn't realize that SLD had it's own MIME type.  It'll most likely be
omitted in future versions, but we should set as you suggest
"application/vnd.ogc.sld+xml" for WMS 1.1.1 and SLD 1.0.0's sake.
