QGIS ignores field inherited from parent feature type in WFS 2.0 services

[denevers]

When loading data from a WFS 2.0 service, the list of fields is missing gml:name and gml:description. It looks like it only considers the fields explicitly provided in the DescribeFeatureType but does not include the field from the parent feature type.

eg: British Columbia Geological Survey WFS

http://apps.empr.gov.bc.ca/geoserver/cgi/ows?SERVICE=WFS

1. Go to Layer/Add WFS Layer
2. Click [New] and use this URL : http://apps.empr.gov.bc.ca/geoserver/cgi/ows
3. You might want to set a Max. number of feature (100), it's a large dataset
4. When done, clikc [Connect] and pick CA-BC BCGS 1:150k bedrock geology layer
5. click [add] and close the dialog
6. right click on layer and pick "properties", then lock a "Fields". 3fields are missing : identifier, name and description

Compare to XML output

http://apps.empr.gov.bc.ca/geoserver/cgi/ows?SERVICE=WFS&REQUEST=GetFeature&VERSION=2.0.0&typeNames=cgi:CA-BC-BCGS-bedrock-geology_v01&count=1&outputFormat=text/xml; subtype=gml/3.2

If we check WFS DescribeFeatureType which returns the schema

note

      <xsd:extension base="gml:AbstractFeatureType">

this comes from this schemas

 <xsd:import namespace="http://www.opengis.net/gml/3.2" schemaLocation="http://apps.empr.gov.bc.ca/geoserver/schemas/gml/3.2.1/gml.xsd"/>

this http://apps.empr.gov.bc.ca/geoserver/schemas/gml/3.2.1/gml.xsd, by the cascade on imports will eventually get to

http://apps.empr.gov.bc.ca/geoserver/schemas/gml/3.2.1/feature.xsd
http://apps.empr.gov.bc.ca/geoserver/schemas/gml/3.2.1/gmlBase.xsd

just how those two files are eventually loaded is through a mind numbing maze.. the chain of imports eventually pulls them both.

AbstractFeatureType (defined in feature) is a subtype of `AbstractGMLType' (defined in gmlBase) and this is where name, description and identifier are defined.

and QGIS does not consider them..

I wonder if this has some connection with the "Override GML Attributes" configuration option in Geoserver https://docs.geoserver.org/main/en/user/services/wfs/webadmin.html setting

For each GML type, there is also an “Override GML Attributes” checkbox. Selecting this (checking the checkbox) will cause attributes to be redefined in the application schema.
