That is one of the differences between the Infoset and the XQuery 1.0
and XPath 2.0 Functions and Operators spec; both define 'canonical'
views of a type-augmented XML document, but Infoset says nothing about
inherited attributes while F&O does describe it:

http://www.w3.org/TR/xpath-functions/#func-lang

and even gives the Xpath to find the current in-scope xml:lang
attribute:

 (ancestor-or-self::*/@xml:lang)[last()]
