says of xml:lang: "(language) indicates the language of the element
content using a ‘tag’ generated according to BCP 47"
http://www.w3.org/XML/1998/namespace says: "Designed for identifying the
human language used in the scope of the element to which it's attached."
http://www.w3.org/TR/xml11/ makes it clear that the scope in question is
lexical scope (in the computer science sense).
My question is whether xml:lang can be assumed to make implications
about the semantic content of the tags as well as the character content.
Or in other words are the two fragments are semantically the same:
<bibl xml:lang="ru"><title xml:lang="en">War and Peace</title><author
<bibl xml:lang="en"><title>War and Peace</title><author>Leo
