I know there is a DTML command to create a folder (or other objects without using the mangaement interface...  For example, I pulled this off the mailinglist archive:
 
<dtml-call "manage_addFolder('aFolderName', REQUEST=_.None)">
 
What I am looking for is how to add an XML document in a similar fashion.  I actually want to call this from within python, but I imagine the syntax will be similar.  Is there a way to do this?
 
Thanks!
