I believe servers have already been implemented and deployed where the live property can vary depending on access path. For example, in order to continue to maintain backward compatibility for a custom property called "parent-path", the server would have to implement bindings in such a way that "parent-path" was calculated from the request address. > >> I'm trying to work through the implications of this, and having a bit >> of trouble. >> Does this imply that a method generating this must be applied both to >> the >> binding against which it was targeted and against some other binding >> to test >> this? or does it imply some mechanism of indicating that a property >> is >> capable fo divergence?

What I meant was that when a new live property is specified (e.g. in an Internet-Draft / RFC), the specification should indicate if the live property may have different values on different bindings. Otherwise, the assumption is that the live property must have the same value on all bindings. Similarly, when a new report is specified, readers may assume that it behaves the same on all bindings, unless the specification says otherwise. I never envisioned a need or utility in having clients apply methods to multiple bindings to test this. I did envision a mechanism to indicate that a property may diverge on different bindings, but I propose this should be in the specification where the property is defined. So there are no issues for discovery/storage. > > > ... > > Regards, Julian > > > -- > <green/>bytes GmbH -- http://www.greenbytes.de -- tel:+492512807760
