the value consists of a single token which may however
contain punctuation
characters, whitespace or word
separating characters. It need not be restricted to
numbers.
The value must conform to BCP 47. If the value is a
private use code (i.e., starts with x- or contains
-x-), a language element with a matching

the TEI Header to document this value. Such documentation may
also optionally be supplied for non-private-use codes, though
these must remain consistent with their
Internet Engineering Task
Force (IETF) definitions.
