I can't believe that the designers of XML intended this interpretation.

If they did, they polluted the specification with significant details
about an essentially useless feature, named entities.  If protecting
the reserved characters was their only purpose, it would have been
simpler to simply state that the numeric references should be used.

I think it much more likely that the intention was that tools for
particular applications should know the entities referenced from the
official DTD (etc.), as well as knowing semantic information (e.g.
section and h allowing an XHTL 2 browser to display the document
outline tree).  I think they were trying to avoid a tool having
to read user provided customisations to the schema, and allowing 
the creation of general XML tools that didn't understand any semantics,
and therefore could do relatively little other than show and edit the
raw structure or display according to a provided style sheet.
