There was a requirement from other WGs that documents be able to
unambiguously refer to the semantics of those WGs' specifications in a
document. For instance, "When I say <rdf>, I mean <rdf> as defined by
the RDF WG of the W3C." Without something performing the functions
that namespaces perform, then browsers would be required to guess
based on the element type names.
This is a matter of record in the XML WG and SIG archives, but sadly,
they are not available to those not members of the W3C.
The purpose of W3C privacy is to give members a concrete advantage
over non-members (otherwise there's no point in joining). But WGs are
required to make their work public within three months of inception;
at this point, it might do much more good than harm to open the older
archives to the public.
