Ben, It appears that the simple feature encodes the data as a MultiCurve. Our schema currently doesn't allow MultiCurve, but I can inquire about a modification. While I don't think there is anything syntactically wrong with encoding multiple LineStringSegments within a gml:Curve, perhaps a gml:MultiCurve is a better choice to indicate the potential multiplicity in this instance.
Thanks for the help. Kevin M.

To test whether this is an app-schema problem, please try publishing the source table as a simple feature and making a WFS 2.0.0 request to see how the geometry is encoded. I have not used Curve geometry types but others on this list have. Kind regards, Ben.
