Typo "attribute in no namespace specified"

[b9chris]

What is the issue with the HTML Standard?

Here:
https://html.spec.whatwg.org/multipage/dom.html#elements

There's a note:
"In XML, an xmlns attribute is part of the namespace declaration mechanism, and an element cannot actually have an xmlns attribute in no namespace specified."

It seems like "in no namespace specified" is a typo, maybe the intended sentence was more like:

In XML, an xmlns attribute is part of the namespace declaration mechanism, and it's possible for an element to have no xmlns attribute, if no namespace is specified.

No this is correct as-is. The xmlns attribute in XML always has a namespace.

I do think the current wording is a little grammatically tricky, tho. It's saying "can't have X specified", but the X is pretty long and doesn't have a clear end, so it garden-paths you a little when you're reading.

I suggest rewording /in no namespace specified/with no namespace/, maybe?

Proposed something slightly more drastic in #11660.
