The new feed has a lot more namespace declarations at the beginning:

Are they all necessary?
Some namespace declarations are duplicated and in particular ns[0-6]
doesn't make sense. Some of those are also redeclared where they are
used. Does this serve a particular purpose?

This doesn't seem to bother our machine treatment of this feed, but my
human brain cringes at useless "information" and duplication.
