EAD Elements
<arc> Arc
Description:
Specifies the rules for traversal among the participating resources in an extended link. Arc uses the attributes to and from to define the traversal between named pairs of resources.
While XML Linking Language (XLink) Version 1.0, which is the basis for EAD linking elements, is a stable document, examples of EAD usage are hypothetical and have not been tested in real XLink-based applications. Those wishing to use XLink are encouraged to consult the specification available online at <http://www.w3.org/TR/xlink/>.
