Hmm, I do:
        <delimited identifier> ::=             <double quote> <delimited identifier body> <double quote>
<delimitedidentifier body> ::= <delimited identifier part>...        <delimited identifier part> ::=
<nondoublequotecharacter>             | <doublequote symbol>
 

As opposed to, say, an empty character string literal:
        <character string literal> ::=             [ <introducer><character set specification> ]             <quote> [
<characterrepresentation>... ] <quote>             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^               [ {
<separator>...<quote> [ <character representation>... ] <quote> }... ]
