This tag is not supported in GML parser from OpenLayers 2.9.1 (I'm using this version), I've been digging in the source code and found this issue in OpenLayers.Format.GML line 141.

The parsing process doesn't throw any error message. In fact, it seems that it reads the GML because while debugging with Firebug I can see that, although the geometry attribute is null, it has read the GML attributes, and they have values. It also has read the fid field correctly. I use this code.
