It should not. This only produces two linefeeds in the resulting FO file that
are happily collapsed into a single space during formatting.

In this case, it should. Probably your formatter does not support shorthand
notations. Try appending a component qualification to the attribute:

<fo:block space-after.optimum="24pt">

However, to give further advices, it would be nice to learn the name/version of
your XSL FO formatter.

Same story: all <xsl:*> elements control spaces in the resulting XSL FO file
only; these hints don't even arrive to the formatter. White space handling in
XSL FO is controlled by a substantial set of specialized properties:
"space-treatment", "linefeed-treatment", "white-space-collapse",
"wrap-option", and "white-space" (the last is a CSS2 compatibility shorthand).

This is an evident bug. I think you should better submit a respective report to
the authors of your tool, and ask for a fix. As an immediate temporary solution,
try putting some dummy text white-on-white ;-), like in the code below:

<fo:list-item-body start-indent="4in">
   <xsl:choose>
     <xsl:when test="normalize-space($wholeName)=''">
       <fo:block color="white">*</fo:block> <!-- placeholder -->
     </xsl:when>
     <xsl:otherwise>
       <fo:block><xsl:value-of select="$wholeName"/></fo:block>
     </xsl:otherwise>
   </xsl:choose>
</fo:list-item-body>

By the way: in your example, list-item-label and list-item-body have equal
start-indents. According to the spec, this is an error: the label and the body
of your list should overlap. If they don't, list implementation in your
formatter is not conformant to W3C specs.

Hope this helps.
