[Zope] Structured Text: avoid <p> around html-tags

Hi, html-tags are allowed in structured text. But they are wrapped with <p>-tags too, which results in non-standard html. How can I prevent that. i.e. list and table elements, that are generated by structured text are not wrapped in <p>'s. (zope 2.6.0) I need to wrap some text in a <div>-box. -- many thanks for your replies, Elena
