GeoServer does not have the capability to create data stores from GML. GML is seen as a data exchange format and is not ideal for querying in the context of supporting WMS and WFS services. GML should be converted to a compatible vector format (using ogr2ogr) and then load the output into GeoServer.
The issue is documented in this thread (circa 2011): http://www.mail-archive.com/geoserver-users@lists.sourceforge.net/msg07665.html
GeoServer does not come built-in with support for GML; it must be installed through an extension.
