Ryan, WFS 1.1.0 defaults to GML 3.1.1 output; you cannot return GML 3.2.1 content unless you use outputformat=gml32 or use WFS 2.0.0. I see you noticed this in a later email. http://docs.geoserver.org/latest/en/user/data/app-schema/supported-gml-versions.html
This looks like a secondary namespace problem, as you note. Also, your mapping for pk_id is invalid as gml:id cannot be an integer; they must be XML NCNames. Furthermore, just use sourceExpression if you want this to be an ordinary property. This is unrelated to the geometry problem. Kind regards, Ben.
