    In contradiction to the protocol specification ("The Sitemap must ... [s]pecify the namespace (protocol standard) within the <urlset> tag."), some sitemaps do not define a (default) namespace. By accepting the "empty" namespace, you'll get URLs even from those sitemaps.

    RSS and Atom sitemap formats do not have strict definition. But if we do not parse as namespace aware, then RSS/Atom files that choose to use namespaces will break. The relaxed compromise for RSS/Atom is to always parse as "namespace aware", but we will only match elements by the localName, accepting any element namespace.
