In the editors draft we now use U+ notation consistently eg

http://www.w3.org/2003/entities/2007doc/sans-serif-bold-italic.html

The unicode standard, where it introduces this notation, says to only pad
with 0's if there are less than 4, so it seems 5 digits is the correct
form for the plane 1 characters, but we are now using 4 digts for BMP
references as you suggested, thanks.
