Is test supportedStoredQueryLanguages required?

[dstenger]

Currently, the test supportedStoredQueryLanguages in "Manage Stored Query"-CC fails against service [1]. The service does not describe the parameter language of the operation CreateStoredQuery.

In the specification we do not find a hint why this is mandatory in the capabilities:

8.3.5.2 Parameter domains (p. 49)
Table 12 defines the parameter domains that may be defined in the capabilities document of a web feature
service.

Table 12 (p. 50):
CreateStoredQuery, language, anyURI

Shall include the value urn:ogc:def:queryLanguage:OGC-WFS::WFSQueryExpression. May also include other
values indicating other languages are supported. This International Standard does not assign any meaning to
or describe any additional values that might be listed.

14.2.2.5.3 Implementation language (p. 82):

The language attribute of the wfs:QueryExpressionText element shall be used to specify the implementation
language of a component query expression.

Servers that conform to this International Standard shall support the value "urn:ogc:def:queryLanguage:OGC-
WFS::WFSQueryExpression" indicating that the component query expression is specified using the wfs:Query
(see 7.9.2.2) or wfs:StoredQuery (see 7.9.3.2) elements.

I believe the phrase "may be defined in the capabilities document" applies to non-standard parameter values that are supported (if any). The description column in Table 12 for CreateStoredQuery (language) states (emphasis added):

Shall include the value urn:ogc:def:queryLanguage:OGC-WFS::WFSQueryExpression. May also include other values...

We added the parameter to the CreateStoredQuery operation in the capabilities. But the test still fails cause of a failure in the xpath of the test. (see #56) .
