[xep-support] column spanning and spacing properties

[Geoff Levner]

I have a page with multiple columns: a block at the top of the page 
that spans all the columns, followed by other blocks which do not.

Using XEP 4.3, the space-after of the first block (which spans all 
columns) and the space-before of the second (which does not) are both 
retained.  Is this intentional?  It was my understanding that the 
transition from span "all" to span "none" should generate a new 
reference area, and so discard the conditional spacing between the two 
areas.

I will attach a simple XSL-FO file to illustrate...

Thanks,
Geoff

	Penguins, yes, penguins. What relevance do penguins have to the

	Sir Alexander Fleming gave the world penicillin. James Watt watched
	an ordinary household kettle boiling and conceived the potentiality
	of steam power. Would Albert Einstein ever have hit upon the theory

	years and years of unremitting study? Of course not. What I said
	earlier about accidental discoveries must have been wrong.
