Hi Sanjoy,
I think it's just the 'normal' limitations you have when setting a variable/id name. Special characters, like parenthesis, are not allowed here.
Peter, I think that's right, but there are small differences. For example, variables in most languages don't allow hyphens, because they are interpreted as minus signs. But ConTeXt references do allow them (and I use them all the time). That may be why I expected free reign to use any characters in the reference (except, as you say, for whitespace!) and wrote my script accordingly to turn problem titles into references (by replacing whitespace with a hyphen). -Sanjoy
