[Zope] "static" includes

Hello, is there a way to include DTML files in a "static" way, i.e. preserving the same namespace the including DTML doc has. If you know what JSP does, this is including static (<%@include ..%>) vs. dynamic (<jsp:include ..>). In the first case the file is included before compiling, that means it is essentially just a simple text replacement or macro expansion. This would make breaking down my DTML documents to smaller parts easier, with the dynamic (that means <dtml-var ..> ??) way I'd need to change all variable references .. thanks --Oliver
