I still haven't memorized routing terminology so I exercised the terminology section.  FYI:

 - The terminology expansion of IS-IS LSP confused me.  Why is LSP "Link State PDU" here and "Label Stitched Path" everywhere else?.  
 - I assume PCED is PCE-Domain -- only the latter is expanded in terminology
 - TLV not defined or referenced (though I realize it's a very well-known TLA in the field)

Section 3.2
 - flooding scope through "L1 area" and "L2 sub-domain" -- should this be part of terminology or an explanation referenced?

Section 4.1
 - If two PCE-ADDRESS sub-TLVs appear, " only the first occurrence is processed and any others MUST be ignored".   With this requirement, what use is it to allow two of PCE-ADDRESS?  If one can be IPv6 and one IPv4 but only the first one MUST be processed, then the other one is useless.

thx -- Lisa

In section 4.2:

Is consistent computation of the PrefL, PrefR, PrefS and PrefY field values important?  If so, are
we depending upon common administration of all PCEs?  Without a more detailed algorithm, it
seems likely a PCC could discover a set of PCEs that used very different algorithms for setting
the preference values.
