#define.EntityKeyNamespace ('http://schemas.microsoft.com/dynamics/2006/02/documents/EntityKey')
#define.EntityKeyListNamespace ('http://schemas.microsoft.com/dynamics/2006/02/documents/EntityKeyList')

Axd: (3) used as standard namespace for all Axd-documents by default:
#define.DocumentNameSpace('http://schemas.microsoft.com/dynamics/2008/01/documents')

Services nodes (2) as described on msdn
