Hi! 
I still favor a comment for [zinh] . . . in spite of misgivings here . . .

CHANGE COMMENT TO (the following is from information from John--the latter I extracted it from John's emails):

> Code 

. . . 

> used to label Unicode combining marks, which "inherit"
> their script property from the . . . character they are combined with. 'Dummy' script { Not used to tag documents ??}

 

However, I do question "Not used to tag documents" I am still totally lost (in spite of Peter's great explanations, below).  What exactly does "Not used to tag documents" mean?  Does it mean not used in the language tag indicating the overall document language, but possibly used somewhere in the document to indicate a diacritic mark on a character (where the display of the diacritic mark depends on the script/character)
  
(Sorry to ask a dumb question & I know this is long but I like lucid explanations that make sense to the unitiated.)
