How easy it is depends on whether you know a priori the GI of the element
that has the attribute you're interested in.  If you do, then 

	(attribute-string "STATUS" (ancestor "book"))

should work.  A more robust approach requires code to find the root element,
a solution for which has previously been posted to this list --
unfortunately I don't have it immediately at hand, but the archives should
show it without too much searching.
