Technical question about ordering of the namespaces and values

One approach we have used (in WPS) is

a) When the resource pool is relatively small (e.g., radio traffic
channels) we serve the  queue based on priority order first, and time stamp
second.

b) When the resource pool is large (e.g. landline trunk groups) we  serve
the queue (amongst all and only the "labeled" calls) by time stamp, without
regard for the actual priority level.

Does the text in section 7.1 PREVENT me from serving SIP messages WITH
regard to BOTH the namespace and value  (and timestamp) in some contexts,
and with regard to ONLY the namespace (and timestamp), but NOT the value in
other contexts?

I can foresee work arounds if it does prevent it, but I would be happier if
that behavior were NOT prevented.

Mike, pay attention to the ordering of two namespaces in the section -
there are ZERO dependencies between namespaces, just that the order within
each namespace MUST be maintained regardless of where one value from one
namespace is places in relative priority order to one or more from another
namespace. Implementors MUST have one order - no matter how many namespaces

are supported at a server/endpoint - to relieve confusion of which is
prioritized over or under another. This is the same rule that applies
within a namespace: there MUST be one order of priority, period (No
wildcards) to ensure interoperability.

snip

cheers,
James
