When given 

a) an XML Schema document S, and 
b) an XML document plus an element E therein (e.g., by an XPath

does anybody know an algorithm to determine the complex type of E as
defined by S? Or, if E does not have a "directly according" complex
type, to determine the complex type of the "nearest" ancestor of E that
has a directly according complex type? Or any algorithm that partly
deals with this problem?

I guess schema validators might implement such functionality, though I'm
not sure whether they provide an interface that can be used from
external programs. Any hints?
