SGML is a language to define markup languages. If start end/or end tags
are omitted, you must know the content model of the element. The content
model is defined in the DTD. If your application stores the content
model in a different format, you don't need a DTD. HTML::Tagset does it
this way. It does this in a manner i don't like, i.e. not conforming to
the HTML 4.01 DTDs, e.g. %HTML::Tagset::optionalEndTag only stores those
elements, where the end tag is 'safely' omittable.

Not really, for example XML documents acutally _are_ SGML documents.
I strongly agree with your design rationale, but I still don't
understand, why the manual implies, that the given construct is legal.
