Summary:

I MUST say that this document is quite MUSTy. I only noted those that caused me
confusion or seemed useless. All of these are either minor issues or nits.
Either way, the document is generally ready.

Major issues:

None.

Minor issues (or might be nits):

In 2.3:

   The validity interval of this trust anchor SHOULD reflect the
   anticipated period of stability...

Are there cases where it wouldn't reflect the period of stability? If so, it
would be good to give an example. If not, then s/SHOULD reflect/reflects.

Similarly for:

   Thus, the entity that issues the trust anchor SHOULD issue a
   subordinate CA certificate that contains...

In this case, that SHOULD might even be a MUST.

In section 4, in the last full paragraph and the bullets, I'm not at all clear
why these are RECOMMENDEDs and SHOULD [NOT]s. If they're not MUSTs, it seems
like you should explain circumstances (at least in general terms) where an
implementation would choose to do deviate from these.

Nits/editorial comments:

In the introduction, the "SHOULD" seems superfluous; it doesn't indicate some
important implementation advice that someone wouldn't otherwise notice in the
protocol. But it's a nit if ever there was one.
