OK, let me reiterate what I said in the last long message. The above paragraph has an interesting grammatical slip in it: the article is missing in front of 'textual reprsentation of that resource.' Now, WHICH textual representation? ANY textual representation? Or THE textual representation appropriate to the datatyping of..... what? Take the example given, where the resource is (I take the liberty of correcting the usual use/mention errors) the number 10. Well, if that were indicated by a decimal then the string "10" would do it, but if it were represented by an octal then you need "12" and if you use a binary then you need "1010". There is no way to say what THE value of rdf:value is for any particular integer, until you specify what datatyping scheme is being used. BUt in the proposed use of rdf:value, there is no way to associate datatyping information with the *value* of rdf:value, only with the subject. Which begs the question. The only coherent interpretation I can give for rdf:value is that it means equality. Then it is meaningful, but kind of useless.
