[xccdf2pdf] nested lists and other issues

[Vladimir G. <vgi...@ds...>]

Hi Gary et al,


Great project!  I used this to validate my content and it found a couple
of little issues.  It produces very nice HTML.  

My content contained descriptions with lists that contained lists such
as 

 <Rule>
   <description>
     <xhtml:ul>
	 <xhtml:li>
           Main list item
	     <xhtml:ul>
		 <xhtml:li>
			Sub List item
		 </xhtml:li>
	     </xhtml:ul>
	 </xhtml:li>
     </xhtml:ul>
   </description>
 </Rule>

And I got 

net.sf.saxon.trans.XPathException:
org.apache.fop.fo.ValidationException: jar:fi
le:/C:/Users/vgiszpenc/Documents/xccdf2pdf-0.90/lib/css2fopnew1_6.jar!/b
e/re/css
/style/css.xsl:382:-1: Error(382/-1): fo:list-block is not a valid child
element
 of fo:list-block.

Do I need a later version of the fop.jar or must I remove nested lists?
Note that the error occurs when trying to produce a pdf but not when
producing xhtml.  In fact, removing the offending nested lists only gets
me far enough to run out of memory.

I can send you the content if you really need it to debug this though it
is still work in progress and not ready for prime time.
