Review comment:
When being the 'requesting client' party asking for a consumer link to
attach and have a dynamic node be created by setting the dynamic flag [and
optionally setting dynamic node properties] that is done via the _source_, as
it is requesting somewhere to consume from is dynamically created for it. The
other side would read the source details requested by the requesting peer and
action things, creating a node, giving it an address, and responding with its
details. When it is sending its 'reply' attach it sets the live details that
now exist also via the source (which from its perspective is now the local
side, which it is authoritative on). The original peer can then read those
details to establish the address and properties of the created node.
For a producer, it is similar but the _target_ is where the details will be
set, as the original peer is requesting that somewhere to send to is
dynamically created for it. The other peer will action this and respond with
details via the _target_ to indicate what actually exists.
