[Zope] Any alternative to &arg in URL?

I am working on a site using both POST and GET forms and I use URL args frequently in the target: action="subfolder/index_html?arg1=spam&arg2=eggs&. .." Using the '&' character in URLs is not legal HTML (4.0-strict). Does Zope recognize other arg separators besides '&'? I don't want to give up the way Zope parses and places the args into the namespace for me. Any thoughts would be much appreciated! John Hermes jhermes@infoglobe.com
