i'm trying to query a WFS for featuretype descriptions (using Geotools
18.1), but the request is failing because the server does not advertise any
outputFormat so I'm seeing the message "Client does not support any of the
server supported output formats for DESCRIBE_FEATURETYPE" appear in my
log, (capabilities snippet and stack trace below)
I have 2 questions:
1. is this a compliant WFS? A complaint server must support "text/xml;
subtype=gml/3.1.1" output to describe features AFAIK, but I'm not entirely
sure it must be advertised, looking at the xsd it seems to be optional...
2. if advertising is not required and below snippet is valid should we get
WFS-NG to try "text/xml; subtype=gml/3.1.1" if the list of outputFormat for
DescribeFeatureType is empty? eg. by returning that as a supported format
from AbstractWFSStrategy#getDefaultOutputFormat(WFSOperationType operation)
or by overloading in StrictWFS_1_x_Strategy#getDefaultOutputFormat(...) or
a specific strategy subclass for this product?
