Well-written specifications will often include statements of fact
that are effectively repeating or summarising definitions or
conformance statements found elsewhere in the specification, making
it easier to understand the specification.

So my authoring tool takes a conforming document, parses that into a
Document, the user adds a proper table with only tr/td elements, and
requests to save the document as HTML. My authoring tool then writes
Document.innerHTML into the file. Which conformance requirement does
my authoring tool definitely violate exactly?
