Why does the spelling (capitalization) of decomposition types differ in DerivedDecompositionType.txt from UnicodeData.txt?

[Peter Constable]

The only point would be to reflect spelling variants used in UCD data files… which may not be of sufficient benefit to bother.

PropertyValueAliases.txt has this entry:

dt ; Nb                               ; Nobreak                          ; nb

What doesn't seem clear from UAX #44 is whether an alias could be added that is equivalent under name matching rules to an existing alias.

It seems like that's allowed, but what would be the point?
