I'm not going to try and understand LaTeX's \DeclareMathSymbol just 
now, but with regard to these particular points: yes, it's confusing, 
but that's how the TeX scanning routines are defined. There are two 
quite distinct things here: the "<hex> notation for numbers (an 
alternative to decimal or octal constants) requires uppercase A-F, but 
the ^^^^<hex> notation for characters (an extension of TeX's ^^<hex> 
notation) uses lowercase a-f. Sorry, I know it's easy to stumble over
