NPE in DomMapperBase using DOM Element with no namespace

Marshalling a DOM element with org.jibx.extras.DomElementMapper caused:

[junit] java.lang.NullPointerException
[junit] at org.jibx.runtime.impl.UTF8StreamWriter.writeMarkup(UTF8StreamWriter.java:96)
[junit] at org.jibx.runtime.impl.XMLWriterBase.startTagOpen(XMLWriterBase.java:196)
[junit] at org.jibx.extras.DomMapperBase.marshalElement(DomMapperBase.java:236)
[junit] at org.jibx.extras.DomElementMapper.marshal(DomElementMapper.java:129)

The DOM document was created with no namespaces.

The supplied test case fails with null element and attribute names rather than a NPE, but is the same problem. The test case uses the existing classes and bindings from the extras test package.

A patch based on the JIBX1_1_6 branch follows:
