[Zope] How to render STX using ZPT?

Hello, I've a small python product. The management screens are all using page templates. Now there needs to be a option to specify one class attribute is in STX format. Is there any easy way to render content using STX rules using ZPT? Current code is: <div tal:replace="structure here/mycontent">Lorem ipsum...</div> Is there any function/keyword etc. that I can use for STX? Thanks in advance Satheehs Babu http://vsbabu.org/
