HTML tags in summary¶
Here we analyze, which types of HTML tags are allowed inside the summary field.
As the content field, the summary field is described as
A natural language summarization of the object encoded as HTML.
This is a somewhat petulant table as most Fediverse applications treat the summary field as a plain text content warning.
Sanitizing fields is desired behavior as seen in Section B.10 of ActivityPub.
