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> | ""
