Linking elements

- defining links

All elements with XLink information contain an xlink:type attribute.

a general linking element is defined using an xlink:type="extended" attribute; this element can contain the following:
a local resource is defined with xlink:type="resource"
a remote resource is defined with xlink:type="locator" and with an xlink:href attribute (an XPointer expression locating the resource)
arcs (traversal rules) are defined with xlink:type="arc":
- both "resource" and "locator" elements can have xlink:label attributes
- an arc element has an xlink:from and an xlink:to attribute
- the "arc" element defines a set of arcs: from each resource having the from label to each resource having the to label

(Note the confusing terminology: a resource is defined either by a "resource" element or by a "locator" element.)

XPointer is described later - just think of XPointer expression as URIs for now...
