main cannot be a child of address

[scottaohara]

The content model for address states:

Flow content, but with no heading content descendants, no sectioning content descendants, and no header, footer, or address element descendants.

However main is also an invalid child of address.

@scottaohara are you sure it's not a mistake about main element?

The main element represents the dominant contents of the document.

so main element could be child of any tag

[scottaohara]

No, it cannot be a child of any tag.

But, per this specific issue, that doesn’t mean that the reverse is untrue. E.g. if the primary content of a document is an address
<main><address>...</address></main>would be appropriate.
