[Zope] STX problem

How can I get structured text to leave everything in <dtml-* > alone? Otherwise I get problems of structured text rendering stuff in the dtml and it changes '' to <code></code> which then upsets dtml which can't then render what is in it. The other option is to remove the code that does <code></code> but I would prefer a better solution then that. Thanks Designing and building web applications http://webme-eng.com
