It's again time to bemoan the decline of the customs
of fine typography. For the uninitiated, dabblers and
Heathens out there:
This is what the space-before and space-after properties
are for.
(BTW spelling skill seems to have been decayed too)

Apart from this, the spec leaves some details open in
the definition of the semantics of <fo:block/>, but it
is *not* the same as a line break in any case.
FOP generates a block area with zero heigth. The effect
of two <fo:block/> is to place two zero heigth block
areas there which cannot be distinguished from having

One possibility to fix this would be to place a &#160; in
the block.
Using space is a bit trickier, probably something like
  <xsl:template match="br">
      <xsl:if test="previous-sibling::*[self::br]
        and normalize-space(previous-sibling::node()[1]
        <xsl:attribute name="space-before">
(Beware: untested)

The advantage of using space is that it would be handled
properly at page breaks, if this were fully implemented
in FOP (the redesigned version will do so).
