Looking at the XML you posted later, I think the literal problem is
very simple: You are registering your provider classes with presumably
a *type* QName RequestedAudiences.TYPE_NAME (although I don't know what
that constant actually has for a value) - but in the XML your elements
aren't carrying xsi:type.  So you need to register the elements with
the *element* name's QName.

Most XML you deal with in SAML doesn't usually carry xsi:type, so the
vast majority case is lookup by element name.  However, if you look at
the core OpenSAML providers, you'll see that we typically register the
providers under both the element name and the type name, just in case.
