Not requires -- perfectly OK to define pipeline-library in no
namespace.

Contrast the _status quo ante_ - pipeline might or might not have
namespaces, who knows when or why.

Not at all -- the import is trivial in either case.

We can't import _anything_ into a library, what's the issue?

It wasn't incorrect, it's just not as well supported by the Schema
spec. as it should be.

That's _worse_ than the _status quo_, in which at least steps have
NCNames.  We're only arguing about pipelines, I hope.

And confusing to users of XML Schema. . .
