Get document name for document element.
The following construct(s) refer to this construct:
tf:getDocname(documentNode $document) => string
The function tf:getDocname is specific to Tamino. It takes a
document node as argument. It returns the document name of the node if present;
otherwise it returns the empty sequence. This is a unique identifier since
document names are unique in Tamino.
In general, you should apply the function fn:root to a node
before passing it the tf:getDocname.
