Re: More on implications of 22.2

[Steve Kille <[e-mail]>]

Kevin,

These are good points.   Let me, for the record, not the converse
case:

1) Here, and in general, the spec aims to use the read operation to
the maximum extent.   This is because it is a reasonable assumption
that all DSA implementations in the context of any level of fanout
will optimimse the performance of the read operation.   

2) Under-specified O/R address has some serious policy implications,
in particular relating to mis-delivery of mail (e.g., a secretary
getting mail that should have been sent to a VP).   In general it is
better to non-deliver mail than to mis-deliver it.   Use of aliases
ensures that matching of under-specified O/R addresses is a conscious
choice, where searching may lead to unpredicatble mis-delivery.

I will add some text which will allow the searching option.   In the
long term, we can use experience to decide whether to mandate one
direction or to continue to allow both.   

I have a couple of errors to fix in this document as well as adding
some text here.  Rather than confuse people with an immediate update,
I suggest  we defer the update until people have read this document.
What do you think?
