"The prefix xmlns is used only to declare namespace bindings and is by
definition bound to the namespace name http://www.w3.org/2000/xmlns/. It
must not be declared. No other prefix may be bound to this namespace
name"

>
> Hi,
>
> Could someone clarify part of the XML Namespaces spec for me?
>
> The spec states that namespace declarations are a special category of
> attribute: "A namespace is *declared* using a family of
> reserved attributes. Such an attribute's name must either be
> |xmlns| or have
> |xmlns:| as a prefix".
>
> So if a namespace declaration like
> xmlns:foo="http://www.foo.com/some.namespace"; is made, and
> that declaration is considered a type of attribute, then:
>
> - the namespace prefix of the attribute is "xmlns"
> - the local name of the attribute is "foo"
> - the value of the attribute is "http://www.foo.com/some.namespace";
>
> But what is the namespace URI of the attribute? What
> namespace does the prefix "xmlns" belong to?
>
> And then you have default namespace declarations, such as
> xmlns="http://www.foo.com/some.namespace";.
>
> - the namespace prefix of the attribute is an empty string: ''
> - the local name of the attribute is "xmlns"
> - the value of the attribute is "http://www.foo.com/some.namespace";
>
> And I presume in this case, the namespace URI would be an
> empty string?
>
> I'm asking because I'm unsure how a DOM method like
> getAttributeNS is supposed to deal with namespace
> declarations. Would xmlns attributes simply be ignored in this case?
