Where can ignored content go?

/ ht@inf.ed.ac.uk (Henry S. Thompson) was heard to say:
| Long-standing question -- are p:pipe and p:document _really_ empty, or
| can they have ignored-prefix content?

That's a good question. I think I'd like to call them truly empty.

                                        Be seeing you,
                                          norm
