Hi Edward,
They don't seem to be required on the Demo MapServer (which is MapServer
version 7.0.6):
http://demo.mapserver.org/cgi-bin/wms_landsat?request=DescribeLayer&service=WMS&version=1.3.0&sld_version=1.1.0&layers=WMS_raster
For SLD 1.1.0, looking at the spec, Table 1 and 2 both list the
"Parameters in DescribeLayer operation request". The required ones
(beyond the standard service/request/version) are:
layers, sld_version
There are no others, either mandatory or optional.
The SLD 1.0 spec is less clear about what's going on, but when I changed
the sld_version=1.0.0, Mapserver excepted telling me only 1.1.0 is
supported.
Hope that helps in some way,
Cheers,
Jonathan

Dear list,
We're currently investigating an error message we get from the WMS
service when we execute a DescribeLayer request. It appears MapServer
requires WIDTH and HEIGHT parameters to be present:
https://github.com/mapserver/mapserver/blob/branch-7-0/mapwms.c#L1705
<https://github.com/mapserver/mapserver/blob/branch-7-0/mapwms.c#L1705>
However, according to the SLD specs, these are NOT required:

Am I interpreting the code or SLD spec incorrectly? Or should I go
ahead and remove these checks and provide a PR?
Many thanks,
Edward
