   - model-element#78 Progress on the spec

I feel like we've made a lot of headway in the last 6 months - It seems
like the ~45 minutes per month that we effectively end up using to talk
about this feature is insufficient to resolve the details necessary to get
a properly-specified feature.

I'd love to establish a more focused meeting - open to all - with a more
regular cadence, so that people aren't coming back to the issues with four
weeks of time to make up for between discussion. AFAIK, the initial WebXR
spec was worked out with a more frequent schedule as well, so there is a
precedent.


   - model-element#71 Supply an Image-based Light file
   <https://github.com/immersive-web/model-element/issues/71> requested by
   zachernuk
   <https://github.com/immersive-web/model-element/issues/71#issuecomment-2440667302>

Somehow I failed to imagine also using CSS to specify this. I quite like
the idea, particularly because it means that it can be changed around with
CSS classes that might indicate color themes etc, and *possibly* to let
things like transition-duration impact the cross-fading between different
environment maps.

One question would be if / how that alters an expected event model for the
loadedness of the asset. Is there a right way to manage that in 2024 (and
beyond?)


   - model-element#72 Specify the view on model contents
   <https://github.com/immersive-web/model-element/issues/72> requested by
   zachernuk
   <https://github.com/immersive-web/model-element/issues/72#issuecomment-2440636997>

Do we want to codify that this happens both *with* DOMMatrix and *in* CSS?
It's not essential to do both, but it does mean things like
transition-duration and CSS Animations have a way to being used.


   - model-element#75 ready and complete events/Promises for responding to
   source file availability etc
   <https://github.com/immersive-web/model-element/issues/75> requested by
   zachernuk
   <https://github.com/immersive-web/model-element/issues/75#issuecomment-2400765096>

Now that we've got multiple folks planning an implementation, we should
check back in on this! Tentatively, I think we need some signaling from the
element about four major moments:

   - Model is parsed and renderable,
   - Model has hit some failure preventing it from becoming renderable,
   - Environmentmap is parsed and renderable,
   - Environmentmap has failed to become renderable.

These could be promises with an await/catch, or events (or both).

If we wanted to pursue a CSS-based mechanism for specifying an environment
map, would that change the recommended presentation of the environment map
states?


   - model-element#99 Presentation as a first-class DOM element
   <https://github.com/immersive-web/model-element/issues/99> - zachernuk

While most of the issues about HTMLModelElement relate *what* it's
displaying (i.e. 3D rendered content, animated and then lit by some
lighting environment), it's also important to consider how it's presented
in the page, alongside other DOM elements. What are requirements that need
to apply?
