In the RelaxNG grammar as published, in fact _ignorable elements_ are
only allowed in subpipelines.  In the DTD as published, they are only
allowed in the prologue of p:pipeline and p:pipeline-library.  I guess
_neither_ of these is correct, but what _is_ correct?

Despite the trickiness of defining this, I think it really should be
"as a child of container elements, or of p:pipeline-library, at _any_
position".  I'm going to rewrite the DTD and XSDL schema to implement
this.
