[Users] Do not work me the DescribeFeatureType query to create a Attribute Store

[Andreas Hocevar]

Are you using a GeoServer url different than '/geoserver/ows' or
'/geoserver/wfs', like e.g. 'http://myhost:8080/geoserver/wfs'? If so,
then your request will be blocked by the browser's Same Origin Policy.
In this case you will need a proxy that makes your wfs available at a
url relative to your application.
