[xsl] Chunking large CALS table in mulitple smaller tables

Hi

Some of the tables I need to process are fairly large (200+ columns).
The publishing software I use will not render tables with this many
columns (unsurprisingly). I need to break these large tables into much
smaller ones, say 10 columns. Each table would repeat column 1 (row
titles). 

INPUT: The real data will have multiple <row> elements.
----------

                <table id="1">
                        <tgroup cols="239">
                                <colspec colname="col1" colnum="1"
colwidth="*"/>
                                ...
                                <colspec colname="col239" colnum="3"
colwidth="*"/>
                                <tbody>
                                        <row id="t1-1">
                                                <entry colname="col1"
id="1">Statement</entry>
                                                ...
                                                <entry colname="col239"
id="239"/>
                                        </row>
                                        ...
                                </tbody>
                        </tgroup>
                </table>


OUTPUT: The colspecs are sequential and I have added new attributes
(oldcolspec & olcolname) to show the original column number)
---------

                <table id="1">
                        <tgroup cols="11">
                                <colspec colname="col1" colnum="1"
oldcolspec="1" colwidth="*"/>
                                ...
                                <colspec colname="col10" colnum="10"
oldcolspec="10" colwidth="*"/>
                                <tbody>
                                        <row id="t1-1">
                                                <entry colname="col1"
oldcolname="1" id="1">Statement</entry>
                                                ...
                                                <entry colname="col10"
oldcolname="10" id="10"/>
                                        </row>
                                </tbody>
                        </tgroup>
                </table>
                <table id="2">

                                <tbody>
                                        <row id="t1-1">
                                                <entry colname="col1"

oldcolname="20" id="10"/>
                                        </row>
                                </tbody>
                        </tgroup>
                </table>

                ...

                <table id="23">
                        <tgroup cols="10">
                                <colspec colname="col1" colnum="1"

                        </tgroup>
                </table>

Any help would be greatly appreciated.
Kind regards.
