The Question of Arcs

Moving Part-way Toward Extended Link Processing

Name	Notes
`xlink:type`	Elements containing the attribute `xlink:type` and the value '`arc`' should also be treated as arcs by XLink processors.
`xlink:from`	Identifies the origin, using a label value from one of the locator or resource elements in the extended link. (If no value appears, defaults to all locators and resources.)
`xlink:to`	Identifies the destination, using a label value from one of the locator or resource elements in the extended link. (If no value appears, defaults to all locators and resources.)
`xlink:arcrole`	Provides an identifier describing the arc. Must be a URI.
`xlink:title`	Provides a human-readable title for the arc, pretty much like the popup text that appears now in some browsers.
`xlink:show`	Provides the options `new` (appear in new window), `embed` (included in text), and `replace` (appears in the current window) for the link content, as well as `other` and `none`.
`xlink:actuate`	Offers the choices `onRequest` (wait for user activation) and `onLoad` (process automatically) to indicate when link processing should happen. `other` and `none` provide additional application-dependent options.
