XML lets you decide which elements you want in your document and then indicate your element boundaries using the appropriate start- and end-tags for those elements. Each red is a complete instance of the color element.
is only the start-tag of the element, showing where it begins; it is not the element itself.
Empty elements are a special case that may be represented either as a pair of start- and end-tags with nothing between them (eg ) or as a single empty element start-tag that has a closing slash to tell the parser `don't go looking for an end-tag to match this' (eg ). [Bob DuCharme]
