The epub:type attribute is now restricted to the SVG `structural`, `shape` and `text` elements: https://w3c.github.io/epub-specs/epub33/core/#sec-epub-type-attribute The HTML restriction existed prior to 3.3 and is already accounted for as far as I'm aware. See [issue 2377](https://github.com/w3c/epub-specs/issues/2377)
