HTML tags for article

Here we analyze, which types of HTML tags are allowed inside the content field of Article type objects. One should expect that a Note, i.e.

Represents a short written work typically less than a single paragraph in length.

see here, should not contain headings h1-h6 or embedded media, e.g. img.

Sanitizing fields is desired behavior as seen in Section B.10 of ActivityPub.
