 Introduction
 ============
 
-Namespace Delegation is an extension which allows server to delegate
-some features handling to an entity/component. Typical use case is an
-external PEP service, but it can be used more generally when your
-preferred server lack one internal feature and you found an external
-component which can do it.

 Configuration
 =============
 
 The configuration is done with a table which map delegated namespace to
 namespace data. Namespace data MUST have a **jid** (in the form **jid =
-"delegated@domain.tld"**) and MAY have an additional **filtering**
-array. If filtering is present, request with attributes in the array
-will be delegated, other will be treated normally (i.e. by Prosody).

 Compatibility
 =============
 
 If you use it with Prosody 0.9 and a component, you need to patch
