Summary:                    rapper doesn't handle  datatype=""and xml:lang=""
properly with RDFa
Description: 
RDFa spec 6.3.1.3 says "there will be situations where the extra mark-up
means nothing, and can therefore be ignored. In this situation an empty
@datatype value can be used to override the XML literal behaviour", but
rapper always generates XML literal when there are child elements.

Also, XML spec 2.12 says "the empty value of xml:lang is used on an
element B to override a specification of xml:lang on an enclosing element
A, without specifying another language. Within B, it is considered that
there is no language information available", so xml:lang="" should cancel
ancestor language information, but rapper gererates lang tag even with
xml:lang="".

(same case for version 1.4.19)
