Tests "wms Get Feature Info Feature Count With Value Of One/Ten" cannot handle non GML responses

[dstenger]

"wms Get Feature Info Feature Count With Value Of One": FEATURE_COUNT is set to 1 but the returned number of feature members is not exactly one!

• count=0 cause GML is expected

"wms Get Feature Info Feature Count With Value Of Ten": FEATURE_COUNT is set to 10 but less than one feature member is returned!

• count=0 cause GML is expected
• I don't find a hint that text/xml is GML in WMS 1.3 and WMS 1.3 DGIWG specifications. From WMS 1.3 (6.6 Output Formats):

Text output formats are usually formatted as Extensible Markup Language (XML; MIME type text/xml). Text
formats are used to convey service metadata, descriptions of error conditions, or responses to queries for
information about features shown on a map.

• Proposal: Enhance test to count the features from the ESRI response format.
