At this late point, we really need to be talking about specifics.
Given that the spec has been updated to remove the use of "valid" in
the description of 'unicode-range' values (I18N-Issue-296) and you
seem to be saying that 'u+....' syntax is acceptable, could you point
out what precisely you'd like changed? Is there something in the
details of the font matching algorithm which precisely describes how
the 'unicode-range' descriptor value is used that you think is
misleading or not clear?
