I believe that it is not too-meaningful to compare an XML document to
a JSON object -- simply because they are waaay too different.

If one compares a JSON object to the XPath 3.1 map data type, it could
be established that these two are almost equivalent.

So, we can substitute the wanted comparison with a comparison between
the XPath map datatype and the document-node() datatype. This would be
more understandable to the XML community.

As for arrays (and nested sequences) -- they are there in XPath 3.1,
and arrays can be contained in maps and maps  -- in arrays, and arrays
in arrays, and sequences in arrays, so there isn't any expressive
superiority for JSON here.
