--------------------------------------

GitHub user HansBrende reopened a pull request:

    https://github.com/apache/any23/pull/88

    ANY23-347 fixed RDFParseExceptions caused by unbound xml namespaces

    My solution to this problem was to strip all xml namespaces from attributes 
and tag names except the "xml:" and "xmlns:" namespaces. I also added a test 
case.
    
    mvn clean test -> all tests pass
    
    @lewismc any comments?
