It was reintroduced, in the form of jsx.

Sure there is some embedded JS in there as well but ignore that and JSX is thr XHTML comeback story.

And jsx was kind of weird because e4x existed (and was never widespread, and implementations of it went away).

I suppose the important part was that jsx needed to be compiled, which means it couldn't introduce any new security issues…
