ConTeXt XML: Nested section elements

One option is to map the <section> tags to \startsectionlevel macros, which can be nested:

\starttext
\startstructurelevel[title=Section heading]
  Some text
  \startstructurelevel[title=Subsection heading]
    More text
  \stopstructurelevel
\stopstructurelevel
\stoptext

The default mapping is that the first level maps to a chapter, the second level maps to a section, and so on. You can change this setting using:

\definesectionlevels
  [default]
  [
    section,
    subsection,
    subsubsection,
    subsubsubsection,
  ]

With the above setup, the first level \startstructurelevel is mapped to \startsection, the second level \startstructurelevel is mapped to \startsubsection and so on until four nested levels.

You can change the style of the document using normal setup commands that change the style of \startsection etc. Here is an example:

\definesectionlevels
  [default]
  [
    section,
    subsection,
    subsubsection,
    subsubsubsection,
  ] 

\setuphead[section][color=blue]
\setuphead[subsection][color=red]

\starttext
\startstructurelevel[title=Section heading]
  Some text
  \startstructurelevel[title=Subsection heading]
    More text
  \stopstructurelevel
\stopstructurelevel
\stoptext

which gives

Based on Aditya's input I can now come up with this solution:

\startbuffer[test]
