That turns out not to be the case.
The meaning of xml:lang="" was introduced by erratum E41 (dated
2002-09-18) between the Second and Third Editions of XML 1.0 (see
http://www.w3.org/XML/xml-V10-2e-errata#E41 ). Even in the First
Edition, there were no constraints on the value of an xml:lang attribute;
productions 33-38, which purported to impose such constraints, were not
reachable from any other production and so were not part of the BNF.
I believe you are confusing empty language tags with empty namespace
declarations, which are indeed a feature of XML 1.1 via Namespaces 1.1.
