Dear draft-ietf-pce-hierarchy-fwk-04 authors,

        After implementing the H-PCE architecture and writing the solution document (currently draft-zhang-pce-hierarchy-extensions-01 ) we found a couple of small issues that could be considered in the framework H-PCE document:

        - Section 1.3.1 and 4.1 mention "Disallow domain-re-entry" as an objective function. I my opinion this should better be a policy. You may want to minimize the total cost, but don't allow to re-enter a domain.

        - The objective functions apply to the whole end to end path. It would be good to have the possibility to specify OF that apply only to the intra-domain paths .  E.g. you may want to minimize the number of transit domains, minimizing the cost of the intra-domain paths (or any other combination you may think). The text in section 4.1 may allow this, but  it is a bit vague "More than one OF (or a composite OF) ....". The specific solution would be discussed later in the solution document.

        Best Regards,

                Óscar
