Strange behaviors in appendix

[Jacques Foucry <jacques@foucry.net>]

Hello,

I redifined some generated in my custom stylesheet :

     <l:i18n xmlns:l="http://docbook.sourceforge.net/xmlns/l10n/1.0";>
         <l:l10n xmlns:l="http://docbook.sourceforge.net/xmlns/l10n/ 
1.0" language="fr" english-language-name="French">
             <l:context name="title">
                 <l:template name="part" text="Partie&#160;%n — %t"/>
                 <l:template name="figure" text="Figure&#160;%n.  
&#160;%t"/>
             </l:context>
             <l:context name="title-numbered">
                 <l:template name="part" text="Partie&#160;%n — %t"/>
                 <l:template name="figure" text="la figure&#160;%n"/>
             </l:context>
             <l:context name="xref-number">
                 <l:template name="figure" text="figure&#160;%n"/>
                 <l:template name="chapter" text="chapitreÊ%n"/>
             </l:context>
         </l:l10n>
     </l:i18n>

Inside my chapter if I make a reference to a figure with <xref  
linkend="foo"/> the generated texte in : figure 1.11

But in the appendix the generated texte remain with an uppercase 'F' :  
Figure A.2

Is appendix use another method ?

How can I change it ?

Thanks in advance,
Jacques
