10.2.5 GetResourceRepresentation exception
If the response of a GetResourceRepresentation request for a tile is unsuccessful, the server SHALL return an HTTP error code that SHOULD be accompanied by an XML
ExceptionReport document as defined in subclause 8.5 of OWS Common [OGC 06- 121r3] and subclause 7.2.2.2 of this document. Determination of what error conditions
map to which HTTP error codes is up to the discretion of the server. If the error condition is due to a malformed request or the resource does not exist for instance in a request
URL with illegal path values, the HTTP error code returned SHOULD be HTTP Error 404 File Not Found.
NOTE For a server where the tile resource files actually exists and there is no specific application
capable of generating specific responses on the fly, HTTP error code SHALL be expected but an XML ExceptionReport document cannot be expected.
10.3 FeatureInfo resource optional in resource oriented architectural style
10.3.1 GetResourceRepresentation request
The ServiceMetadata document in the resource oriented architectural style may contain a list of Layer elements and each layer that is available to be retrieved in this architectural
style and is queryable SHALL have one or more ResourceURL elements with the resourceType attribute set to FeatureInfo and a template attribute. In this RESTful
approach the template attribute contains a URL template that can be converted to a URL by using a template processor and then get the expected FeatureInfo in the format
specified by the attribute format by requesting the resource with a standard HTTP GET.
