Atom is a container format, not a processing language. There's no harm
in an element you don't understand or recognize in an atom feed.



We could adopt a rule that says if px:foo doesn't have a declaration,
then it's ignored but that would prevent us from catching simple
errors (like typos or pipelines that fail to import a relevant
library). What's more, the pipeline might run perfectly fine but give
entirely incorrect results.

So I think we need a mechanism that allows the author to say "this is
data that I want in the pipeline, not a step". We could (and did try)
to do this with an "ignored-prefixes" attribute, much like
extension-prefixes in XSLT, but it was complicated and unweildy.
