The Recommendation says "COMMENT tokens do not occur in the grammar (to
keep it readable), but any number of these tokens may appear anywhere
outside other tokens." If the "-" and the "22em" are two tokens, then
adding "immediately" somewhere is not sufficient to clarify that between
these particular tokens COMMENTs are not allowed, given the quoted text.
