Hello Amir,

In my opinion, using the @lang attribute to set direction is a bad idea. The language tag is not an explicit indicator of the direction of content. It may, of course, imply the direction. But it is a poor indicator compared to either explicit direction or to first strong (auto direction).

Having @lang start a new isolate might be worthwhile, though, since one language embedded in another might very well have different directional characteristics and there is no reason to require users to input both attributes if the content does not inherently require more complex markup.

The direction/dir transition plan is nice.

It's a bit disappointing, though, that neither of the following
suggestions was considered:
1. Make any element with an explicit lang or dir attribute
bidi-isolated by default

2. Apply the direction according to language

Is there, maybe, a plan to consider this in the future?
