=====

* The draft assumes some kind of ordering requirement between namespaces. From my reading of RFC4412, this is not the case.

"Thus, a message (or a call) with the following Resource-Priority
header value:

dsn-000001.8

for example, MUST NOT ever receive preferential treatment over a
message, for example, with this Resource-Priority header value:

dsn-000010.0

because they are two difference namespaces"

e.g.

Consider an RP actor that supports both the namespaces, dsn-000001 and dsn-000010. It could maintain an ordered list which contains

dsn-000001.9
dsn-000001.8
dsn-000010.9
...
dsn-000010.0

and this is a valid priority order according to section 8.2 of RFC4412. Given this, why would this be considered invalid behavior if dsn-000001.8 DID receive preferential treatment over dsn-000010.0? This might be a major misunderstanding on my part. If so please correct me.
