Each xmlns... attribute means that, for the RDF element and any elements it
contains, those are the prefixes used to qualify specific namespaces of
elements (and attributes if required).

xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
means that any element prefixed with rdf: (including the rdf:RDF element
belongs to the namespace http://www.w3.org/1999/02/22-rdf-syntax-ns#.

xmlns="http://purl.org/rss/1.0/"
means that any element with no prefix at all belongs to the
http://purl.org/rss/1.0/ namespace.
