[Zope] differentiate dtml method from document

Hi - Is there a suffix I can add to DTML Methods that would then be recognized by the ZODB upon creating an object externally like from within Dreamweaver? If I create an object externally and call it SOMEFILE.DTML - it is recognized as a DTML Document. Ok, good. But, now I want to create a file that will be recognized as a DTML METHOD. Any ideas? Thanks David Kovach
