why so complex
\startbuffer[test]
<a>
<nattable frame="on">
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
</tr>
<tr>
<td>5</td>
<td>6</td>
<td>7</td>
<td>8</td>
</tr>
</nattable>
<nattable frame="off">
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
</tr>
<tr>
<td>5</td>
<td>6</td>
<td>7</td>
<td>8</td>
</tr>
</nattable>
<nattable frame="no">
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
</tr>
<tr>
<td>5</td>
<td>6</td>
<td>7</td>
<td>8</td>
</tr>
</nattable>
</a>
\stopbuffer
\startxmlsetups xml:testsetups
\xmlsetsetup{main}{a|nattable|tr|td|}{xml:*}
\stopxmlsetups
\xmlregistersetup{xml:testsetups}
\startxmlsetups xml:a
\xmlflush{#1}
\stopxmlsetups
\xmlmapvalue {nattable:frame} {on} {on}

\xmlmapvalue {nattable:frame} {no} {off}

\placefigure
[here,none]
{}
{
\setupTABLE[frame=\xmlval{nattable:frame}{\xmlatt{#1}{frame}}{on}]
\bTABLE
\xmlflush{#1}
\eTABLE
}
\stopxmlsetups
\startxmlsetups xml:tr
\bTR

\stoptext
In x-cals.lua / mkiv you can see an example of pure lua solution. It
boils down to applying a function the the whole table element.
