SQL Transformer nested queries not working

[Tuomo L]

When doing this:

<sql:execute-query>
  <sql:query>some query on 1st level...</sql:query>
  <sql:execute-query>
    <sql:query>some query on 2nd level...</sql:query>
  </sql:execute-query>
  <sql:execute-query>
    <sql:query>some other query on 2nd level...</sql:query>
  </sql:execute-query>
</sql:execute-query>

...the SQL-transformer outputs nothing. So, if there is  more than
one queries on some other level than the first one, nothing is created for
output.

Is there a way to get this working?
