No, it won't. A variable is an abstraction; it can have a different
meaning in different contexts. But an xref is concrete; it always points
to a specific marker in a specific file. 

You can't create an xref that says, "go get the contents of the first
Title pgf in whatever file is first in whatever book you're in."
Theoretically, I suppose the functionality could be made to work --
although it would be ugly/messy. At any given moment, the xref would
point to the location identified by whichever book file you last updated
from. If you open the file from outside of any book, the xref couldn't
be validated/updated. 

In any case, the functionality doesn't exist and, IMHO, it wouldn't
offer any advantages over using a variable if it did. 

Of course, if you quote me, you may hear from my lawyer. ;-)
