XREFs in table cells not hypenating

Hi all,

I'm using Docbook 5, Docbook XSL 1.73.2, and 
RenderX XEP. I've got the main hypenate parameter for my style sheets set to 
"true" and I've also hardcoded the hypenate="true" property into the inline 
element containing the output of the XREF element, and yet...not hypenating, not 
even breaking lines. Any ideas? A sample of the output FO is 
below:

    <fo:table-cell padding-left="2pt" 
padding-right="2pt" 
padding-top="2pt"
                                
padding-bottom="2pt" 
keep-with-previous="always"
                                
keep-with-next="always" 
wrap-option="wrap"
                                
border-bottom-width="0.5pt" 
border-bottom-style="solid"
                                
border-bottom-color="black" 
border-right-width="0.5pt"
                                
border-right-style="solid" 
border-right-color="black">
                                
<fo:block font-weight="bold" 
font-family="sans-serif"
                                    
hyphenate="true" font-size="9pt" 
keep-with-next="always">
                                    
<fo:block space-before.optimum="6pt" 
space-before.minimum="4pt"
                                        
space-before.maximum="8pt"><fo:basic-link
                                            
internal-destination="ae122848">
                                            
<fo:inline hyphenate="true">Section 3.1, "Write 
Request"</fo:inline>
                                        
</fo:basic-link> or 
<fo:basic-link
                                            
internal-destination="ae132805">
                                            
<fo:inline hyphenate="true">Section 3.4, "Stripe Write 
Request"</fo:inline>
                                        
</fo:basic-link></fo:block>
                                
</fo:block>
                            
</fo:table-cell>

Cheers,
Jeff.
