Subject: Pass the parsed DocBook content along the state of readDocBook

Having access to the entire document will be needed when handling
elements which refer to other elements. This is needed for e.g. <xref>
or <link>, both of which reference other elements (by the 'id'
attribute) for the label text.

I suppose that in practice, the [Content] returned by parseXML always
only contains one 'Elem' value -- the document element. However, I'm not
totally sure about it, so let's just pass all the Content along.
