I've got a student who's attempted to use the hex representation for a few
character entities, and the validator is throwing up an interesting error: 

http://validator.w3.org/check?uri=http%3A%2F%2Fmembers.xoom.com%2F_XOOM%2Fne
t_miner%2F02%2Fcharent.html

eg: 

 <LI>Hexadecimal: <STRONG>f7</STRONG> &#xf7;

  Error: "XF7" is not a function name


Aside from likely interoperability problems in using the hex version --
what is the validation issue here?
