[css3-text] Tibetan tsek justification

When justifying Tibetan texts, is it acceptable under any of the 
'text-justify' values to use tsek marks as justification? Is this 
traditional method even used in electronically composed texts? Is it 
possible, before the CSS3 Text module reaches Proposed Recommendation, 
to add a note explaining the eventual verdict?

Does anybody care?

(For those who don't follow the tsek question, I refer you to The 
Unicode Standard 4.0.1, section 9.11, "Tibetan"; see the subsection, 
"Traditional Text Formatting and Line Justification".
