I don't see how. The example does work in ypaste. "followed by ns-char"
obviously allows _more_ than "followed by ns-plain-safe(c)". This does
not matter, since the following character is _not_ consumed by this
production, and is left to be consumed by a normal ns-plain-char
production later.

How so?

literal: |2 
	  value
	folded:
	   !foo
	  >1
	 value

Vs.:

	%YAML 1.2
	---
	!!map {
	  ? !!str "literal"
	  : !!str "value",
	  ? !!str "folded"
	  : !<!foo> "value",
	}

Seems the same to me... If the !<!foo> is throwing you off, see "Verbatim Tags".

Have fun,
