>
> {quote}Contrary to the interface specification, Saxon does not supply an
> empty document when the value is null. This is because XPath 2.0 allows the
> context item to be "absent" (null). So Saxon executes the XPath expression
> with the context item undefined.
> {quote}

> So in case of xpath expression is executed against a null body or header,
> saxon throws an NPE
