Hi Ethan,

My message is related to your response from this post. ([MAP IGN integrated to MAP SUITE](https://community.thinkgeo.com/t/map-ign-integrated-to-map-suite/5759/19))

I’m sorry, I do not see how to change anything with getcapability.  
I understand that the GetCapability returned by IGN does not meet a standard and so the thinkgeo Wmts layer can not read it.  
By putting a breakpoint in the code, in sourceurl I have “[http://wxs.ign.fr/?Service=WMTS&Request=GetCapabilities](http://wxs.ign.fr/?Service=WMTS&Request=GetCapabilities)”  
I can read it with xdocument but after that, how can I change \<ows: SupportedCRS\> EPSG: 3857 \</ ow: SupportedCRS\> by its equivalence that meets the standard …urn:ogc:def:crs:EPSG:6.18:3:3857?

But it’s mostly how to return a new uri that contains the GetCapabilities with this value there?

Thanks a lot for your help.

Regards

Steph.
