Grammar Overview

Based on the formal production rules from the YES spec:

<ELEMENT>   → <SYMBOL> <NAME> <KEYVALUE>
<SYMBOL>    → ! | @ | # | ε
<KEYVALUE>  → <VALUE> | <KEY>=<VALUE> | <KEYVALUE> <DELIMITER> <KEYVALUE> | ε
<DELIMITER> → space | ,
<RAWTOKEN>  → <TOKEN> | "<TOKEN>" | ⌈<TOKEN>⌋

Reserved characters that cannot appear unquoted in element names: !, #, @, ,
