Any attributes for XML is optional, it will be only used when
necessary -- that is the advantage of XML over  MARC which you need to
specify if the subfield is required or optional.

The use of language attribute is needed when the element or field is in
different language from the one that metadata uses, or it carry
specific importance to the user or system usage (limited search by
keyword language/text...)

The best way to control what the language of the data is in should be
done by the metadata, not computer software for good reasons.
