That's a bit of a simplification. You MUST understand XML, namespaces, and namespace prefixes to run the IdP period. That is the price of admission.

What changed is that some of the older schemas and namespaces were combined and collapsed to enable wider/near-universal use of a single XML namespace bound to the default namespace of the document so that prefixes are no longer needed when no additional namespaces are used, but that itself is not universal either. There are still other namespaces that come into play in some of the configurations and certainly in Spring files.
