No. “domain” is a prefix bound to a given namespace.
That namespace has a namespace binding provided by a URI that, seems(?) to have some sintax inside.
Those are elements (nodes) defined on the namespace I’m not yet sure if they are elements inside the declaration, or somekind of attributes of a given name space that we access by using :
urn:ietf:params:xml:ns:domain-1.0
There’s no such think as childs of namespace. The 2) answers this.
Please, if the above IS NOT precise, let me know. Please.
