Hi, I agree with Christian on the parses/doesn't parse classification.
My understanding is as follows: 3 and div are non-delimiting terminal symbols, and hence must be separated by a whitespace. This is specified here: http://www.w3.org/TR/xquery-30/#id-terminal-delimitation 12!(12 div.) doesn't parse because the . after a QName requires a whitespace (. and - are listed as exceptions in the above link). The same applies to div-. 1<<a>2</a> doesn't parse because << would be recognized as a token. 1<<<a>2</a> parses though. I hope it helps!
