Addressing Scope Identifiers and Anonymous Terminus

When a scope identifier is used in an link target address and I try, for instance, to
attach to “target:(example.com)”, I’m practically asking for a link route to example.com’s anonymous terminus. Thus, implicitly, for a container that supports routing, any scope-identifier maps to a logical routing node.

 

Now, when I finally get to example.com, “target:(example.com)” isn’t describing the anonymous terminus because the address isn’t empty.

 

Because in AMQP 1.0 2.6.3, the target is explicitly permitted to update the properties of a link as it sends its accepting
attach frame, I now plan to mandate in the addressing spec that containers that claim ownership of a given scope-identifier always strip that scope identifier from the updated link properties as they respond to
attach.

That then results in “target:(example.com)” turning into “target:” and is therefore the anonymous terminus.

 

Thoughts?
