What is a namespace ... really?

it's simple - if one allows it to be.

the thing named is the collection of names.

the syntax for the names for these collections of names is that which is
permitted for uri's.

of all things about namespaces in xml, this is one aspect which obviates
interpretation and permits no prevarication: that's exactly and all they wrote.

nb. while it's not static, it's also not intangible. any given ns-conformant
processor must have a quite concrete model of what a given namespace is at
every point in time. (neglecting the "null" namespace, for the moment.) since
the uri "names" a namespace only once an attribute-binding has appeared, its
only meaning is exactly that which the processor models.
