It absolutely does not, because this is application layer markup. The 
XLink syntax only defines the existence of a link between two 
resources, the meaning and behavior of that link is a question for 
the particular application and the local processing environment, and 
this is how it's intended to be.

XLink cannot and should not attempt to define this. XHTML most 
certainly should define the meaning of links within its domain. And 
other applications will define the meaning and behavior of links 
within theirs.
