Proposal: role="subheading"

[carnoxen]

What is this?

The subtitle for its parent heading element.

Example

<h1>title <span role="subheading">and subtitle</span></h1>

Reason for proposal

It might alternate <hgroup> element.

I know that role="doc-subtitle" exists. But "subheading" is more consistent with heading role element.

[jnurthen]

As we have doc-subtitle I don't think this needs to remain open.

@jnurthen not disagreeing but have you seen w3c/html-aam#501 ? There might be something missing for p in hgroup equivalent.

I’m reopening this for discussion, as presently doc-subtitle maps to a heading, so that doesn’t really solve the issue without further work (and is that necessary? Is either necessary?)
