[Zope] ZCatalog: How to use a subattribute as index?

Hi, I would like to use ZCatalog to catalog my ZSQL methods, in particular, I am interested in search ZSQL methods with templates containing a given table or row name. Give a ZSQL method "mySqlMethod", the raw template is in the attribute "mySqlMethod.template.raw". You can see my trouble, now. How can I catalog an index that is a subattribute of an attribute?
