XML is throws error invalid char 9082

[greeshma]

create X-DOCUMENT hDoc.
CREATE X-NODEREF hRoot.
hDoc:CREATE-NODE(hRoot,"12","ELEMENT").
This statemt throws an error "X-NODEREF or X-DOCUMENT CREATE-NODE got an error: An invalid character was
specified. (9082)
"
Cant we add numeric character as first element?

As far as I know XML tags and attibutes must start with a letter.

Have a look here: http://www.w3.org/standards/xml/core
