[CITE-Forum] Is an empty "returnFeatureTypes" attribute valid in stored query creation?

Hi,
I'm looking at a failing test that issues the following request:

<CreateStoredQuery xmlns="http://www.opengis.net/wfs/2.0" service="WFS"
version="2.0.0">
  <StoredQueryDefinition xmlns:xsd="http://www.w3.org/2001/XMLSchema"
                          id="urn:example:wfs2-query:GetFeatureByName">
      <Title>GetFeatureByName</Title>
      <Abstract>Returns feature representations by name. The name value
must occur in a gml:name property.</Abstract>
      <Parameter name="name" type="xsd:string">
         <Abstract>Name of feature instance (required)</Abstract>
      </Parameter>
      <QueryExpressionText xmlns:fes="http://www.opengis.net/fes/2.0"
                           xmlns:gml="http://www.opengis.net/gml/3.2"
                           isPrivate="false"

 language="urn:ogc:def:queryLanguage:OGC-WFS::WFSQueryExpression"
*                           returnFeatureTypes="">*
         <Query xmlns:ns42="http://cite.opengeospatial.org/gmlsf"
                typeNames="ns42:EntitéGénérique">
            <fes:Filter>
               <fes:PropertyIsLike escapeChar="\" singleChar="?"
wildCard="*">
                  <fes:ValueReference>gml:name</fes:ValueReference>
                  <fes:Literal>*${name}*</fes:Literal>
               </fes:PropertyIsLike>
            </fes:Filter>
         </Query>
      </QueryExpressionText>
  </StoredQueryDefinition>
</CreateStoredQuery>

GeoServer complains about returnFeatureTypes, in particular:

"StoredQuery references typeName sf:EntitéGénérique not listed in
returnFeatureTypes"

Now, the attribute is mandatory and specifications example has a non empty
value (also available here:
http://schemas.opengis.net/wfs/2.0/examples/StoredQuery/CreateStoredQueryExample.xml
)
The spec does not address directly the empty value case:

14.2.2.5.2 Declaring the returned feature types
The returnFeatureTypes attribute on the wfs:QueryExpressionText element
shall be used to specify the
feature type(s) that each component query expression returns.
If more than one return feature type is listed, this indicates that the
corresponding component query
expression returns a join tuple composed of the listed feature types.
The returned feature type names shall be from the list of feature type
names that a server advertises in its
capabilities document (see 8.3.3).


So... can anyone clarify this situation?

Cheers
Andrea
