It sounds like a good move editorially. What is the impact on implementations? All I can see is that an implementation that does "simple datatype entailment" would now be free to NOT see that {ex:b ex:q "string"^^xsd:string} entails {ex:b ex:q _:b._:b rdf:type xsd:string. } (as you have in appendex A) because it would be free to not recognize xsd:string. That seems like a perfectly acceptable change, to me. I can't imagine any implementation which would do simple datatype entailment and *not* recognize xsd:string -- that just wouldn't make sense in practice. BTW, we fixed the parsing rules, so you can leave off the space before the period in Turtle.
