That is very well possible.  Sounds like a word I would not have recognized....
So would on Org-mode grammar start like this?

-------------------------------------------------------------------------------

<headline> ::= "*"+ <opt-todo-keyword>
                    <opt-priority-cookie>
                    <title>
                    <opt-tags>

<opt-todo-keyword> ::= <whitespace> <todo-keyword> | ""

<opt-priority-cookie> ::= <whitespace> <priority-cookie> | ""

<opt-tags> ::= <whitespace> <tags> | ""



<todo-keyword> ::= "TODO" | "DONE"

<priority-cookie> ::= "[" "#" <priority> "]"

<priority> ::= "A" | "B" | "C"                   

<tags> ::= ( ":" <tag> )+ ":"

<whitespace> ::= " " <opt-whitespace> | "\t" <opt-whitespace>

<opt-whitespace> ::= <whitespace> | ""
