I tried to explain in my last message why I thought tailoring the definition of extended grapheme cluster was not the right approach, and suggested an alternative approach.  Let me try to put it more succinctly: the clusters of glyphs between which Thai/Lao letter-spacing inserts space are different from the clusters of glyph corresponding to extended grapheme clusters.  The spec for letter-spacing should allow for the fact that for some scripts the typographically correct points to insert letter space do not correspond to boundaries between extended grapheme clusters.

Yeah, I understand what you want to explain. But practically speaking:


 1.  Use A, but implementers can tailor A in any way they need
 2.  Use anything, but use A as baseline

These two look the same thing to me. No?
