Base URI of result tree should be the base output URI
When XSLT transformation output produces a result tree that is delivered as a tree, the base URI of the document node should be the base output URI. The spec doesn't say this literally, but it's a reasonable thing to expect, so that relative URIs within the content of the result tree can be properly resolved.

A patch has been committed; the effect is that when a base output URI has been set on an XsltTransformer, and no base URI has been set on the XdmDestination to which the result is set, the base URI of the XdmDestination is implicitly set to the base output URI of the XsltTransformer.
