Caption duplication in CALS tables

Hello,

When I try to insert a caption in a CALS table, the html output  
contains its caption twice. For instance, the following valid docbook  
document produces a table with the caption in the title as well as in  
its "normal" place.

Is there a way to suppress the caption occurrence in the title?

I am using docbook 5, with Saxon 8B.

Thank you

Fabrizio Gotti

             </caption>
        </table>
     </chapter>
</book>

produces an html table like this:
Table 1.1. Sample CALS Table (long title)

This is a caption, it should appear only once.

[empty line]

This is a caption, it should appear only once.
