I'm sorry. This is relevant. First of all, language tags should but do
not have to be ISO 639 language tags. Although some early parsers were
confused about this, xml:lang="Français" is well-formed.
Secondly, even if we stick to ASCII this is an issue. Consider
xml:lang="it". This is the same as xml:lang="IT" when compared in an
English locale but not when compared in a Turkish locale. In Java.
"it".equalsIgnoreCase("IT") is *false* in Turkey.
