Re: Fwd: Error in RDFa Core 1.1 examples

Ben,

Unless I am missing something, I think that you are reading the examples 
in section 2.2 wrong or you have not quite understood how the @prefix 
attribute works.

In RDFa @prefix is used to declare prefix mappings.  It takes the 
special format PREFIX ':' ' ' xsd:anyURI - this is defined (along with 
the data types of all of the RDFa attributes) in section 5.  @prefix 
does not take CURIEs.  It defines the prefix mappings that are later 
used by CURIEs.

In all of the other places in section 2.2 where I looked I did not see 
any use of prefix: IRI other than in the declaration of prefixes.

If I have missed something, please let me know.  Thanks!
