r.org/protocol/feature-neg} namespace.

1. Introduction

The protocol defined herein enables Jabber entities to negotiate options for specific features. These features could be negotiated between any two endpoints on the Jabber network, such as two clients, a client and a component, two components, a client and a server, or two servers. The protocol is generic enough that it can be used whenever options need to be negotiated between two Jabber entities. For examples, Stream Initiation (XEP-0095) [2], SI File Transfer (XEP-0096) [3] or Stanza Session Negotiation (XEP-0155) [4].
