I think You actually did more than just copy the 'id'. In a "DTML Document"
id is a "method" that needs to be called to get the actual id.
I believe that when you say

let x=y

Zope checks to see if 'y' is callable, and if so, it is called and 
'x' is set to be the result of that invocation.

try:
<p>
This is the <!--#var id--> Document.<br>
My id is reported to be:<dtml-var "testid(id())"><br>
</p>

and see if that works for you.
