Hello Michael,

thank you and the XML Schema Working Group for looking into this issue. The
i18n Core Working Group discussed your response on our call yesterday, see 
In general, we agree with your resolution. We have two comments left, see

First, we think you do not need to say "successor" for the reference to BCP 47. 
BCP 47 always refers to the latest RFC used for language identification and
matching. The term "successor" would only be needed for a reference to such an
RFC, e.g. "RFC 4646 or its successor".

Second, for the ABNF, we agree that you don't need to refer to the ABNF defined
in RFC 4646. However, it would be great if you could add a reference to the
notion of "well-formed language tags", saying (even non-normatively) that
checking of well-formedness of language tags is what an XML Schema processor
might consider. The principle of well-formedness for language tags leads
directly to the ABNF, see section 2.2.9. "Classes of Conformance" of RFC 4646
for the necessary definition. In this way, you would promote the right
behavior, even if you do not update the regular expression for the language
data type.

Thank you,
