Fwd: RDF 1.1 Turtle - W3C Recommendation 25 February 2014 --- Missing declaration of empty prefix in examples 24 and 26 ?

Hello RDF Working Group,

my first mail had accidentally been sent via the wrong e-mail account, as I am using a family shared Mac Book.

Sorry for the inconvenience!

Kind regards
Jürgen Pfundt

> The same is true for example 26 which explains example 25. The empty prefix should be declared for predicates :p and :p2 and objects :q and :q2.
