Yes, but a bnode or a URI can refer to a literal. So if those can refer to a literal,
then instead of writing

[1] _:n1 owl:sameAs "hello";
     numLetters 5 .

Why not also allow one to write

[2] "hello" numLetters 5.

?

That is what I meant. 

In any case one can always map [2] to [1], so I am not sure
the costs of allowing [2] need be that high. Every current implementation
could just parse [2] and write it out as [1].

No?

It just seems that [2] is a more concise way of writing things, and
it is conceptually cleaner.
