As I understand it, the operational purpose of hreflang (I have no idea
which browsers do this, if any) is to set the Accept-Language: header in
any HTTP transaction used to fetch the document.  That way you can link
to a specific-language version of a document.  The XInclude analogue is
the accept-language attribute.
