I wonder, having just revisited our discussion of anyURI and its relation to
the relevant RFCs, whether we should cultivate a looser coupling to the Unicode
database.  I can think of two or three variants that might simplify life:

(1) Just leave the reference at 5.1.  The spec allows implementations to
support later versions of Unicode, and we don't have a pressing need to require
them to be up to date.

(2) Move the reference back to Unicode 3 or so, on the same logic.

(3) Make the Unicode reference wholly generic and specify that the version of
Unicode supported is implementation-defined.  

(4) Move the table of block names (and any other version-sensitive information
about Unicode) to a non-normative document, and in that document provide not
just the block names for the current version of Unicode, but record their
changes (so users and implementors have a better chance of deciphering problems
in the area). 

Note that (3) is compatible with each of the others, or with updating the
minimum Unicode version to 6.0.
