That (SGML OPEN/ Oasys XML catalogues come to mind) or even
the Web browser cache and similar, for site-specific files.

It would be in the same namespace as the parent.

E.g. if you had said orderedlist implied a docbook namespace,
then a lst element, and a para within that would be ins the same
namespace without you having to say anything.

Validation using an existing schema would involve first
adding the namespace URLs explicitly (e.g. with XSLT,
a transformation that would read the namespace file and
apply the namespaces to the instance), so that then if
you'd forgotten an element that mattered, you'd find the error.
