[xsl] How to make auto row-spanned table

[Toshihiko Makita <tmakita@xxxxxxxxxxxxx>]

Hi list,

I'm making a stylesheet that converts DITA documents to XSL-FO. Usually 
a table is authored with entry/@morerows attribute. But some table has 
no @morerows attribute. My challenge is to generate row-spanned table 
from this table automatically by stylesheet.

For your reference I uploaded sample PDF to Yahoo! Box.

(To download the PDF, click "cc&c3c-c<c	" button.)

The first table is input table. It has no @morerows attribute. The 
second result table is desired output. The first column and second 
column and third column has row spans.

Can someone give me an advice about how to implement this?

Regards,
