Added DomDocumentCache::createDocument overload enabling document naming

* previous createDocument method used default name "content"
** this led to problems when using xalan::XalanNode as transformation input
** the parameter-less createDocument overload now creates a unnamed xercesc::DOMDocument
* changed external function implementations accordingly
