I think this has to do with the role of xml:lang: it it used to label
natural language for the document content, that is the attributes and
children of a document. You might label natural language not for document
content in that sense, but for other kinds of information. For these
cases, you should use a different attribute. We have also the related note
in the BP:
"Note: If you need to specify language as data or meta-data about
something external to the document, do it with an attribute different from
xml:lang. For more information see the article xml:lang in XML document
schemas"
