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.

> .... Leading zeros are omitted, unless the code point would have fewer
       than four hexadecimal digits for example, U+0001, U+0012, U+0123,
       U+1234, U+12345, U+102345.
