[DISC] typo in message grammar?

["John D. Ramsdell" <ramsdell@linus.mitre.org>]

It appears there is an error is the following section of the grammar
associated with <simple-chars>.

<ident> := <simple-chars>+					<---
<quoted-string> := '"' <string-chars> '"'
<line> := any number of characters, but no newlines.

<simple-chars> := '' | <simple-char> <simple-chars>		<---
<string-chars> := '' | <string-char> <string-chars>

Should this read as follows:

<ident> := <simple-chars>
<quoted-string> := '"' <string-chars> '"'
<line> := any number of characters, but no newlines.

<simple-chars> := <simple-char> | <simple-char> <simple-chars>
<string-chars> := '' | <string-char> <string-chars>
