I18N-ISSUE-400: collation lang processing should refer to BCP47 ⓟ

In Section 13.1.3 I find:

--
The lang attribute indicates that a collation suitable for a particular natural language should be used. The effective value of the attribute must either be a string in the value space of xs:language, or a zero-length string. Supplying the zero-length string has the same effect as omitting the attribute. If a language is requested that is not supported, the processor may use a fallback language identified by removing successive hyphen-separated suffixes from the supplied value until a supported language code is obtained; failing this, the processor behaves as if the lang attribute were omitted.
--

This describes a fallback that is identical to RFC4647 Basic Filtering [1] used in BCP47. However, no reference is provided to BCP47.

I'd suggest explicitly referencing BCP47 here and specifying fallback by reference.
