Hi Daniel, the EPSG problem has resolved itself, I only had the problem when running php in a shell, not running on the webserver, so it probably had something to do with PROJ_LIB.
Wrt to OGC:WMS versus WMS, all the examples in the 1.0 spec use OGC:WMS instead of WMS, see: http://www.opengeospatial.org/docs/03-036r2.pdf I have opened up the following bugs: 1) cannot open WMC which misses an XML header: http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1691 2) context code does not support true/false for xs:boolean http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1692 3) context 1.0 write code uses WMS instead of OGC:WMS http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1693 Best regards, Bart -----Oorspronkelijk bericht----- Van: UMN MapServer Users List [mailto:[EMAIL PROTECTED] Daniel Morissette Verzonden: dinsdag 28 februari 2006 21:07 Aan: [email protected] Onderwerp: Re: [UMN_MAPSERVER-USERS] Web Map Context interoperability problems 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.
