I think that's because even if the data interchange format is strongly typed, as a consumer you often still must expect _anything_. I've yet to work on a project that handles XML where we have a XSD prevalidation step that makes the reading of some deeply nested XML tag feel safe. Unless we count XML <-> data object binding back in the java days. Not sure that felt any better...
