How about doing it in a slightly different way:

<page name="page">
    <html name="10">
         <value>Test</value>
         <if><value>2></value><equals>1</equals></if>
    </html>
    <coa name="20">
          <html name="10"><value>test2</value></html>
    </coa>
</page>

In outher words, a typoscript object type would corellate to XML
element type, and the identifier will be stored in "name" or any other
attribute.

The bigger problem, is, however, "stray" definitions, where you, say,
misspell "config" or some other config variable, and, while it will be
perfectly normal TypoScript it will not produce the results you want.

If you are validating the syntax only I would say XML->DTD validation
is not the way to go. I don't think you can enforce some of TypoScript
syntax rules through DTD (for example, multi-line values in ( ) ).

I would probably look at other syntax parsers available (bison, lexx?).
