REQ-3: Provide resource-oriented API

REQ-5: simpleProfileCRS84Tile URL template

At least one layer in WMTS services implementing this profile SHALL have at least one URL template of resourceType "simpleProfileCRS84Tile" for fetching tiles in image/png or image/jpeg format.

REQ-6: Support GoogleMapsCompatible scale set

The identifier is urn:ogc:def:wkss:OGC:1.0:GoogleMapsCompatible. See OGC 07-057r7, E.4.
