Not much. However in the XML world people have come to make the
distinction between describing the structure of a document (location of
elements and attributes) and specifying the actual values in the
document (textual content of elements and attributes).

Since the types of the Street, Country and PostalCode elements is
xs:anyType meaning they can have any content I'm assuming Rich means
there isn't enough information there to do much processing with.
