I wasn't aware there was anything more to syntax highlighting than what you are calling "lexical highlighting" - what I think of as "syntax highlighting" consists of coloring comments, string literals, and reserved words differently than identifiers or punctuation marks. So, I gather that there must be some editors which use more complicated schemes; can you point me at an example?
