No, now that we've decided that existential quantification is part of RDF, there *is* expressive power in properties of literals (strings, XML content constants, ...): Consider: <http://www.w3.org/> dc:title _:s. _:t charmod:lengthNumeral "15". that's true in interpretations where the/a title of the W3C home page is longer than 15 chars, and false in other interpretations. -- Dan Connolly, W3C http://www.w3.org/People/Connolly/
