FYI, I have produced a new version of my registry lookup tool. In addition
to helping you find subtags and lookup the meaning of subtags, it now helps
check the well-formedness of a language tag.

The tool provides access to all currently defined subtags, and fully
integrates the new extlang subtags.

Parsing language tags. In addition to trying to make the user interface more
friendly, I also added the ability to parse hyphenated tags and discover
their structure and check for errors. I’m not claiming with this release
that the new parser field tests all the corner cases, but it should provide
reports for most of the typical errors.

It reports errors for the following:

- subtags that are not in the registry (by type)
- incorrectly ordered subtags
- duplicate variant tags and multiple tags of other types
- overlong private use subtags

Try this example.

It doesn’t yet handle extensions, but then there aren’t any valid ones to
handle yet anyway.

I hope that’s useful to someone.
