Where, if anywhere in Unicode 4.0.1 is the normative property Grapheme_Link used? I can find its definition easily enough, and references to UAX#29, but the last time it was used there was way back in tr29-1 and the current version is tr29-6. Are there plans for this property, or can it be safely ignored as I prepare a draft proposal for an improved PUA? (It doesn't make much difference, as right now it looks like supporting this property would require one or two code points for the proposal.)
