I don't know what that means.
What I tried to say is, if you need ID_Start, then parse ID_Start from
DerivedCoreProperties.txt. That's more stable (and easier than parsing the
pieces and deriving
# Lu + Ll + Lt + Lm + Lo + Nl
# + Other_ID_Start
# - Pattern_Syntax
# - Pattern_White_Space
yourself.
For example, at least one of the derivation formulas (for Alphabetic) is
changing from 6.3 to 7.0.
