> XML (the data structure) needs a non-XML serialization.

That's YAML, and it is arguibly worse. Here's a sample YAML 1.2 document straight from their spec:

    %TAG !e! tag:example.com,2000:app/
    ---
    - !local foo
    - !!str bar
    - !e!tag%21 baz

Nightmare fuel. Just by looking at it, can you tell what it does?

Some notes:

- SemWeb also has JSON-LD serialization. It's a good compromise that fits modern tooling nicely.

- XML is still a damn good compromise between human readable and machine readable. Not perfect, but what is perfect anyway?

- HTML5 is now more complex than XHTML ever was (all sorts of historical caveats in this claim, I know, don't worry).

- Markup beauty is relative, we should accept that.
