5fixture at all: it refuses a manuscript whose byte and scalar offsets never

6diverge, because such a manuscript cannot tell the two coordinate systems apart.}

9@p{An EMPTY STRING is not an id. It is truthy in Scheme, so the obvious

10`(if (string? v) v #f)` accepted it, skipped the missing-id diagnostic, and

16the positional branch and become a phantom positional field whose value was the

17keyword object; on a node whose FIRST argument was such a keyword, the node

18silently lost its id and reported that its first argument was not a string.}
