I don't understand the logic of the data-attribute yet. Shouldn't there be a reference to which the attribute refers?
In that case to the h1-element. That means, for me it would be logical to have:
> <h1>heading</h1> <p data-h1="subheading">subheading</p>


But then the semantics is away for the element attribute itself.
I think I have a lack on use-cases here to can think of if this could work and is useful.
