Is DEL OK?

Section 2.2 says, " Legal characters are tab, carriage return, line
feed, and the legal graphic characters of Unicode and ISO/IEC 10646."
But production [2] for Char allows characters in the range
[#x20-#xD7FF], which includes #x7F (ASCII DEL), which I did not think
was a "graphic" character.

Is DEL a valid Char, or not?

Thank you.
