When saving the list of namespaces and classes a particular type is contained in we have to save the class name and any template args it includes separately. This allows us to mangle the names easier. And we now search for type names to see if they follow this pattern template_name<template_args>::embedded_class. If we are using a template embedded class we need to create attributes for the embedded class.
