There has been considerable attention paid to the document, which now
resides at http://www.w3.org/2007/OWL/wiki/PlainLiteral

First, obviously the name has changed from rdf:text to rdf:PlainLiteral
(or maybe rdf:O(+>

Second, the way that older applications are protected from
typed literals with datatype URI rdf:PlainLiteral
(http://www.w3.org/TR/rdf-concepts/#section-Graph-Literal) in surface
syntaxes is that such literals are illegal in surface syntaxes that also
have a syntact for RDF plain literals.  Instead of using 
typed literals with datatype URI rdf:PlainLiteral in, e.g., RDF/XML,
applications must use the syntax for plain literals.

The needed changes to the WG documents are very slight.  As far as I
know, only two changes are needed:
1/ Mapping to RDF needs a small change in the forward mapping to effect
   the above prohibition.
2/ Syntax needs a small change in Section 5.7 to tie the plain literal
   abbreviated syntax to just rdf:PlainLiteral (and not also to

I checked the other documents and didn't see the need for any other

My view is that the rdf:PlainLiteral document is now acceptable as far
as OWL is concerned, and the WG can vote to publish it or even advance
it to CR.
