Hi,
Perhaps I have not found the complete solution yet, because I just
noticed that a href attribute is used where I would expect a xlink:href
attribute. Also the xlink namespace definition is missing. Am I still
doing something wrong?
Thanks for your reaction.
Regards,

Hi,
To answer my own question:
1) changing SurfacePropertyType into GeometryPropertyType in the
schema and creating an empty Geometry does the trick!
2) looking at the code I discovered that the check on existing id's is
done based on the id of the feature NOT on the id of the geometry! I am
able to produce different gml:Polygon elements with the same gml:id.
[ Since I am using a DefaultFeatureCollection I cannot test if
duplicate id's are handled correctly, because the FeatureCollection
does not accept duplicate id's.
3) Remains one issue: the gml:boundedBy element of the featuremember
refering to the geometry of the first is NULL; is there a way to repair
this? (Or to leave this element out?)

Andrea,
is XSIdRegistry turned off for simple features, for performance and
memory reasons? I recall a discussion ...
Kind regards,
Ben.

Hi,
I have a simple GML3 Application schema which I use to encode a featurecollection to a gml document. However I do not succeed in getting duplicate gml:id's in geometry elements to be replaced by xlink:href attributes. Even worse: duplicate id's are accepted while I thought that the XSDIdRegistry would take care of that.
I am using geotools 2.6.3
Any suggestions?
