It is quite easy to make DTML Methods "Content-Type" aware:

  Give it a "content_type" attribute. All the machinery is present
  to provide the correct Content-Type HTTP header, as soon
  as there is a "content_type" attribute.


  The following two external methods can manage a "content_type"
  attribute of DTMLMethods (for DTMLDocuments, a standard
  property works well).
  
  def getContentType(obj):
    '''return content type of *obj*, 'None', if not available.'''
    o= getattr(obj,'aq_base',obj)
    return getattr(o,'content_type',None)
  
  
  def setContentType(obj,type):
    '''set content type of *obj* to *type*.'''
    o= getattr(obj,'aq_base',obj)
    o.content_type= type
  

An alternative is to give the DTMLMethod's extensions.
If, e.g., a DTMLMethod has an id with a '.txt" extension (suffix),
then its default content type is "text/plain".
