public comment: navigational values on action URLs?

[Stefan Hepper <sthepper@hursley.ibm.com>]

Is it really intended that you can set navigational values on an action 
URL or is this an oversight in the URL BNF?

I think result of the action should set new navigational values, but not 
the submit of an action URL. Encoding new nav values will reset whatever 
nav value other portlets have set in the meantime after the URL has been 
generated.
Is there really a use case to support this?
