It doesn't seem to me that your statement addresses Frank's
statement.  Unless I'm mistaken, Frank is talking about custom
extensions; and you seem to be referring to the evolution of
HTML proper.

I think XML is better-suited to extension (in the sense of
extending a standard "schema" with your own element types, or
embedding data of one type in a document of another type) than
SGML, but I'm no expert.

What is the SGML feature that one would use for similar
semantics as XML namespaces provide?

Is there existing SGML work that does what XML Schemas aims
to do?
