I am now using xtable to have an XMLish document to store a table. How I can embed ConTeXt code like $\Delta{}N_{\text{test}}$
in the external XML file file with the table? In other words, having mathematical notiation in the table header?
I tried various things such as:
\expanded{\xmlflush{#1}}
1. Have you looked at the cals table module?
No. I was able to find some references to CALS and ConTeXt with Google, but no documentation for the module you describe.
A simple example I found online:
\usemodule[cals]
\starttext
\startbuffer
cals:table
    <tgroup cols="1">
       <colspec/>
       <thead>
          <row>
             <entry>Any text</entry>
          </row>
       </thead>
       <tbody>
          <row>
             <entry>Any text</entry>
          </row>
       </tbody>
    </tgroup>

\stopbuffer
\processXMLbuffer
\stoptext
Are there advantages for CALS tables in ConTeXt vs. the xtable solution? 
I have R scripts (a programming language) that produce HTML tables and 
write them to files. Not very robust or complete but it works. This is 
easy to use with xtables and \xmlprocessfile . But I am interested in a 
more well-defined format such as CALS tables, of course. Anything I can 
also easily embed in DocBook documents would be very nice.

2. Can you provide a example for your problem?
No, not at this time, because I am very pressed for time now. But I will come back to this later.
When the content of the cells is normal context code you can use \xmlflushcontext instead of \xmlflush.
Thank you. Do you know of a quick way to map an attribute, say the "id" 
of the "table" element to a ConTeXt ID/name? (So that I can refer to the 
table with \in.) At the moment there are no table numbers/descriptions 
for xtables at all in my document. I am using this code based on Thomas 
Schmitz's example in the xtables manual:

     \startxmlsetups xml:testsetups
         \xmlsetsetup{main}{TABLE|TR|TD|TH}{xml:*}
     \stopxmlsetups
     \xmlregistersetup{xml:testsetups}

     \startxmlsetups xml:TABLE
         \startembeddedxtable[\xmlatt{#1}{id}]
             \xmlflush{#1}
         \stopembeddedxtable
     \stopxmlsetups

     \startxmlsetups xml:TR
         \startxrow
             \xmlflush{#1}
         \stopxrow
     \stopxmlsetups

     \startxmlsetups xml:TD
         \startxcell
             \xmlflush{#1}
         \stopxcell
     \stopxmlsetups

     \startxmlsetups xml:TH
         \startxcell[background=color,backgroundcolor=gray]
             \xmlflushcontext{#1}
         \stopxcell
     \stopxmlsetups
