[mapguide-users] deleting feature source

[Jackie Ng]

Instead of your regular resource id string (ie
Library://Path/To/yourfeaturesource.FeatureSource ), use a session-based
resource id string instead (ie
Session:yoursessionid//yourfeaturesource.FeatureSource ) 

Just remember that resource ids are just references, so you have to
create/upload the underlying resource data itself.
