When you say "developer," are you speaking of content authoring?
Usually, I consider that term applies to the engineers that produce user
agents, and I think it important to use terms carefully here, so I'm
pointing out my confusion.

If I'm correct in my interpretation of what you say ...

I believe we've established that there's  excellent support in some, and
nonexistent support in others.

I'm far more interested in the digital publishing industry than in
novice authors. The industry that produces textbooks by which our
children are educated, the industry that produces the technical
publications that our professionals rely on, should not be required to
rely on hit and miss "best guess" user agent heuristics.


Let me now ask you a question ...

What's the concern you have with existing lanb markup? Why this sudden
interest? What are you seeking to achieve?

I'm glad we agree.

So what? A BMW costs more than a Volkswagen, clearly. Are you saying
there's no place in the world for BMW?

What are you trying to achieve?

If you can kindly speak to the reasons behind your concern, I think we
will be better able to answer this question.
