                 and also includes specialization logic (see 
                <a href="defining-extensions.html#context">Extension Context</a> ). The full path for the element is [url]#[elementid]. If there is no #, the Element
                 id is one defined in the base specification. When an element has assigned type,
                 the type is also an assigned id for this element, which means that the type can
                 also be used here.
