A bit of a controversial question,
but here's my take:
Namespaces can act as "collectors"
of XML constructs (elements/attributes/datatypes) for some purpose. I say "some"
purpose because it is left open to how namespaces are used.
For example, I know of one e-forms
product that uses namespaces as a way to route information in a form to multiple
systems by using the namespace as a mechanism - that is, all information that
was entered into the form into fields that are associated with constructs (in
the XML schema "behind" the form) that are in a given namespace (got that so
far?) are routed to channel A, which processes information for that
Hope that helps--
