Hi Bart,
Could you please file a bug and Julien will have a look and provide more
precise answers?
Quick comments about the issues that you raised:
About the EPSG code not being recognized, we've used 4326 before and I
don't thing the pszValue+5 implies that the EPSG code needs to be 5
digits, I think it's there to skip the "EPSG:" prefix. It has to be
something else, we'll need to check further with this
About #1: you're right that this is missing
About #2: MapServer 4.9 should spit out "OGC:WMS" for v1.1.0 contexts,
and "WMS" for 1.0.0 ... I didn't double-check the specs, but I think
this is the correct behavior.

Hi list,
I am trying to use a WMC document generated by Ionic in Mapserver, but
cannot get it to work (no layers in map object). The Ionic context
validates in Oxygen.
First problem, Ionic does not use a XML header for the context, so
Mapserver comes back with:
PHP Warning: [MapServer Error]: msLoadMapContext(): Invalid XML file
(/data/geoservices/apps/geoservices/htdocs/ionic.cml)
in /data/geoservices/apps/geoservices/htdocs/wmc_ionic.php on line 5
So I added the XML header by hand. Then the following problem occurs:
PHP Warning: [MapServer Error]: msLoadMapContext(): Unable to set units
for projection ''
Could it be that the Mapserver code assumes a 5 letter SRS EPSG code? If I
use e.g. 28992 it runs fine.
sprintf(pszProj, "init=epsg:%s", pszValue+5);
I have seen a few other potential problems in the Mapserver code:
1) the parsing code for queryable etc. assumes to get a 0 or 1, whereas
true or false are also valid values for xs:boolean
2) when outputting a WMC, Mapserver uses WMS for the value of the service
attribute of Server, whereas the OGC example (on schemas.opengis.net) as
well as Ionic use OGC:WMS
<Server service="OGC:WMS"
I have attached the context if somebody is interested to try this out.
Best regards,
Bart
