M7A3: Either in-json or out-yaml is wrong

[hvr]

IMHO, out-yaml is wrong, as the intent of that example in the spec is clearly to show an example with only 2 docs. (also note that ... on their own don't introduce a new document)

I'm a bit suprised btw that the canonical right-hand-side of example 9.3 doesn't read

%YAML 1.2
---
!!str "Bare document"
...
%YAML 1.2
---
!!str "%!PS-Adobe-2.0\n"

(notice the ...) like the similar one from example 9.5 had.

---

PS: To expand a bit more:

The YAML 1.2 spec says (emphasis added)

YAML uses three dashes (“---”) to separate directives from document content. This also serves to signal the start of a document if no directives are present. Three dots ( “...”) indicate the end of a document without starting a new one, for use in communication channels.

moreover,

[205] l-document-suffix ::= c-document-end s-l-comments

So the # No document comment would be part of the l-document-suffix production.

Moreover,

[211] 	l-yaml-stream 	::= 	l-document-prefix* l-any-document?
                              ( l-document-suffix+ l-document-prefix* l-any-document?
                              | l-document-prefix* l-explicit-document? )* 

encodes that multiple consecutive occurences of l-document-suffix count as one.

Hence we got only two documents, and thus test-event stating

+STR
+DOC
=VAL :Bare document
-DOC ...
+DOC
=VAL |%!PS-Adobe-2.0 # Not the first line\n
-DOC
-STR

is in fact correct.
