d91e61955542f8019867a559206cd3ff163684ec language: pass user options in matched tag
Applications should always use a single matched Tag per user session
for selecting the display language and language-specific services.
So far, the tag returned from a match was the original supported tag
and as such did not include any user options specified in the -u
extension. It was hard for a user to add this as well, as the Match
method does not return the preferred tag that resulted in the match.
The Match method now copies in the -u extension of the user's tag.
It is assumed that the set of supported tags do not specify a -u
section, which is fair to assume as these are typically needed only
in the next phase of a match.
Also:
- updated documentation
- changed interpretation of grandfathered tag en-GB-oed.
