FOLLOWUP:  Here's the relevant paragraph from the XSL-FO 1.1  
specification (http://www.w3.org/TR/xsl11/):

If a conditional space-specifier ends a reference-area or line-area,  
then it is suppressed together with any other conditional space- 
specifiers which consecutively precede it in the sequence. For  
purposes of this rule, a space-specifier U consecutively precedes  a  
space-specifier V if it U precedes V and U and V are separated in the  
sequence only by conditional space-specifiers and/or space-specifiers  
whose computed minimum, maximum, and optimum values are zero.

To me, that suggests the last space-after in a reference area (e.g.  
fo:block-container) should be suppressed.  Or am I misunderstanding  
things?
