This analysis is right on. Does this demonstrate a hierarchy of natures
similar to a type hierarchy? Such a hierarchy of natures is distinct from a
classic type hierarchy as it cuts across types incorporating content-types,
document types and (perhaps in another example schema types).

Yet this heirarchy is not obvious from examining the URIs themselves and so
we need a way to express its definition.

Perhaps in english as:

 resources which have a nature of http://www.w3.org/TR/html4/ are defined to
inherit the nature of
http://www.isi.edu/in-notes/iana/assignments/media-types/text/html

and perhaps in RDDL as:

<rddl:resource
        xml:base="http://www.w3.org/TR/html4/"
        xl:arcrole="http://www.rddl.org/purposes#definition"
        xl:role="http://www.rddl.org/natures#nature"

xl:href="http://www.isi.edu/in-notes/iana/assignments/media-types/text/html"
><p>Resources which have a specific nature of HTML 4.0 i.e.
http://www.w3.org/TR/html4/ have a more general nature of text/html i.e.
http://www.isi.edu/in-notes/iana/assignments/media-types/text/html
    </p>
</rddl:resource>
