/*
Capabilities are advertised in messages sent by each peer during
session establishment. When the NETCONF session is opened, each peer
(both client and server) MUST send a <hello> element containing a
list of that peer's capabilities. Each peer MUST send at least the
base NETCONF capability, "urn:ietf:params:netconf:base:1.0".
<hello>
<capabilities>
<capability>URI</capability>
</capabilities>
