Thanks for punting that to the ML.
Wrt the paragraph beginning "In general...", it has been revised:
# In CSS, the paragraph embedding level must be set (following rule HL1)
# according to the direction property of the paragraph’s containing
# block rather than by the heuristic given in steps P2 and P3 of the
# Unicode algorithm. There is, however, one exception: when the
# computed unicode-bidi of the paragraph’s containing block is
# 'plaintext', the Unicode heuristics in P2 and P3 are used as
# described in [UAX9], without the HL1 override.
Wrt referring to the HL* rules, the bidi spec does not appear to require
such references, only that modifications to the algorithm conform to
those rules. However I have added the references as you request to help
clarify the intent.
Wrt using "must" everywhere, whether one agrees or disagrees with the style,
it is not a habit of the CSS specs to do so, and statements without the
modifier are nonetheless normative per

Since this sentence is only a few paragraphs below the section that
defines them, I haven't added a link. But all of them are now talking
about rule HL3, so this will help create that correspondance.

This is now specified explicitly.
Comment #2 is handled separately, see thread at

Please let me know if this sufficiently addresses the comment.
