When I just start to play with xml/context, I realize a test for table
(i'm still playing with it) in which I write something like

<table>
<!-- ... other elements -->
<row>
<entry role="setupentry[nx=2,background=color,backgroundcolor=red]">
blahh blahh
</entry>
<!-- ... other elements -->
</row>
<!-- ... other elements -->
</table>

and define

\defineXMLpickup [entry] [role=]%
%%Open tag
{\expanded{\beforesplitstring{\XMLpar{entry}{role}{}}}\at [\to\Type%  
% get  ..options..]
\expanded{\aftersplitstring{\XMLpar{entry}{role}{}}}\at
[\to\rawOptions%  
% get  ..options..
\expanded{\beforesplitstring{\rawOptions}}\at ]\to\Options%  
\doifelse{\Type}{setupentry}%
{%then
\expanded{\bTD[\Options]}
}{%else
\bTD%  
}}%
%%Close tag
{\eTD}

Is your way, Simon ?
