Correct numbers: 2 required 9 not recommended 34 optional! (note this includes rdf:XMLLiteral as an optional, so the total should be one more than the number of XML Schema builtin simple datatypes) (I have opted for "seventeen billion" rather than "17179869184" as the value of 2^34) >> [[ >> One WG decided to use the built-in datatypes from XML Schema in their >> specification. However, on inspection it become clear that a few of >> these were inappropriate, and that some implementors thought the cost of >> implementing all of the rest prohibitive. Thus the WG identified: nine datatypes as not recommended, and two as required, leaving the other thirty-three as optional.
