Points to an internal link target by identifying the value
Identifies the XLink actuate behavior of the link:

An application should traverse from the starting resource to the ending resource only on a post-loading event triggered for the purpose of traversal.
The behavior of an application traversing to the ending resource is unconstrained by this specification. The application should look for other markup present in the link to determine the appropriate behavior.
