General questions, IDL and delegation of something that isn't provided

[leobalter]

Questions by @bkardell , originally from #6

• Is the first code example missing a <template>
• Where do these get added in IDL?
• What happens if you delegate something and it isn't provided? What if it is provided implicitly? (like, using a itself?)
• Are all of the names. simply boolean attributes? That is, their mere presence is true? ariadelegateslabel=false - what happens - with that?

Is the first code example missing a <template>

this is now improved. I first used an example simulating the rendered shadow-root but now the examples are reusable if someone copy and paste the HTML and JS parts.

I don't have these answers yet.

Are all of the names. simply boolean attributes? That is, their mere presence is true?

They are boolean attributes.

ariadelegateslabel=false - what happens - with that?

IDK, I'll see that.

fwiw https://html.spec.whatwg.org/#boolean-attributes is what I meant, specifically. There are attributes which work both ways, I was just asking which it was intended. Sometimes the string false works, sometimes it is "a boolean attribute" by that definition

Let's move this to different issues, one for the IDL question and another for what happens when you delegate something that isn't provided.

About the booleans, we might end up going with attributes that allow a list, so I guess that can be discussed as part of #3.
