Hi John,
The block-container with the zero-length fo:leader is generated by the 
<?dbfo-need height="0.00in" ?> processing instruction.  I would suggest you 
just remove that.  The dbfo-need mechanism does not work in FOP, and a 
zero-height value should have no effect anyway.  The page break should come 
automatically because the image is too big to fit in the space remaining on 
the first page and will be forced to the next page.  Or from the 
break-before attribute you add.

Regarding the attributes, I'm not sure which customization layer I provided. 
8^)
One approach might be to add a template like this (untested):

<xsl:template match="mediaobject[ancestor::appendix[@role = 
'external-doc']]">
  <fo:block font-size="0" line-height="0" break-before="page" 
break-after="page"   start-indent="0" end-indent="0">
    <xsl:apply-imports/>
  </fo:block>
</xsl:template>

This will match only on a mediaobject contained in your special appendix. 
It outputs a block wrapper with the necessary values, and then generates the 
normal mediaobject output in it by using xsl:apply-imports.
