Okay, something like this (in an external method, you could also use
DTML directly but it's clunkier) would do the trick:

# UNTESTED CODE! This is only to point you into the right direction;
# no idea if it'll work.

# call this like this: http://mysite/mydoc/0/addComments
# (so on the 'far' node of the document)

def addComments(self, REQUEST):
    # get a list of all entries
    children = self.objectValues('entry')
    # go through them
    for child in children:
        # create comment node for child
        comment_node = self.getOwnerDocument().createElement('comment')
        # add it and get the node we just added (note that I'm not sure
the
        # latter is still necessary with the latest alpha of
XMLDocument; it
        # used to be necessary due to acquisition trickiness)
        comment_node = child.appendChild(comment_node)
        # set the text content of the comment node by adding a text node
        text_node = self.getOwnerDocument().createTextNode("My text")
        comment_node.appendChild(text_node)
