that's a bug in mapcache, it turns out service= is optional for wms
1.1.1 . I've just pushed a fix to the repository.

Can't help you here. WMTS is so little used that each vendor probably
has more or less tolerance on the conformance of the capabilities doc.

how can you tell that, you first stated WMS wasn't working ? If I
remember correctly, a blue tint on png was a display bug IE had on
some png types back in the glorious days of ie6...

you can't, formats are defined at the server level, not the layer
level in wms. Mapcache however ignore the FORMAT= wms parameter, and
returns the image format that was configured in your mapcache.xml
(This is by design, the server maintainer is more knowledgeable than
the requester as to which format is more optimal for a given layer)

This is another wms limitation, the root layer must contain the
configured projections of all its child layers. The child layers are
however advertised only for the SRS(s) they are individually
configured for.
