OK... I suppose that makes sense. The way I'm used to seeing
it specified is

  <li> means list item

and if the sender says <li>, the reader is allowed
to conclude that the sender meant list item, and
if the sender didn't mean list item, then the
miscommunication is the sender's fault.

I suppose it's sort of six of one, half dozen of the other...
I suppose I can just squint my head and read "<li> must be used
as a list item" as "<li> means list item" and substitute
"the document is non-conforming" for "the miscommunication
is the sender's fault".

In a strict mathematical sense it's very strange
that the same sequence of characters
(or DOM structure) could be conforming when sent by a sender
who meant one thing and non-conforming when sent by a sender
who meant something else... but I suppose I can live
with that too if I squint and read generously...
i.e. read "the document is non-conforming" as
"the sending of the document is non-conforming".
