Hi Peter, others,

Thanks for working on clarifying the grammar!

Do you mean #x23 in the above two rules?  I'm not sure what a double quote
would do there, but a line comment might make sense.

Now that end-of-line characters are made explicit in the grammar, I'm
wondering whether there are implications for the way in which line numbers
are reported by processors?  E.g., if a parser encounters a bug on a
certain line it is nice if the user is able to go to that line and fix the
bug there.

Most processors will use Unix and/or Windows end-of-line conventions and
will report an error on the second line of the following content (i.e.,
missing end-of-statement character):

```
<x:x><x:x><x:x>.#xD#xA<y:y><y:y><y:y>
```

But according to the N-Triples grammar, the missing end-of-statement
character is not on the second but on the third line.
