Normative status of UCD fields

The editorial committee recommends that all of the General Catagory
properties, plus the case mappings (in UnicodeData + SpecialCasing) be made
normative. There are enough programs and other standards that need to rely
on these values, and refer to them normatively, that the current status of
'informative' is proving to be a roadblock.

Historically, one of the reasons for making case mappings informative was
that they vary between countries. However, SpecialCasing supplies a
mechanism for handling this, so there is no barrier to making them
normative. Like the bidi properties (also normative), they can be overriden
in the presence of a higher-level protocol.
