How to combine multiple policy sets?

["Satoshi Hada" <SATOSHIH@jp.ibm.com>]

Hi,

The answer to the following question
should go into the Errata document.

Q: 
How does each policy combining algorithm defined in
Appendix C 
combine multiple policy sets 
(and a mixed sequence of policies and policy sets)?

Here are the links to the related discussion.
In my understanding, the answer is that
a <PolicySet> is 
treated exactly like a <Policy>
in all the policy combining algorithms.
