[Simple] Partial Publication of elements with more than one instance possible

[Pankaj Munjal <pankaj.munjal at gmail.com>]

Hello all,

According to the Presence RFCs, there can be a few elements like
<note>, <cipid>-<display_name> that can have multiple entries.
However, they don't have ids associated with them to identify the instances.

If my client is using partial publish to change values of one of such
instances, then which instance shall be updated on the Server?
(Assuming that my initial PUBLISH had more than one instance for such
field)

Is this scenario documented in some RFC/draft?

Kindly suggest!

Regards,
Pankaj
