I stopped going with what I thought worked, and
investigated what actually did work.  A working servlet is
below.  I get the impression that nobody develops module
based servlets, as the documentation omits that you need to
require servlet-sig.ss to get request-bindings.   The
online documentation also doesn't mention the helper
procedures are in servlet-helpers.ss

(module stephen mzscheme

  (require (lib "servlet.ss" "web-server")
           (lib "servlet-sig.ss" "web-server")
           (lib "servlet-helpers.ss" "web-server"))

  (provide interface-version timeout start)

  (define interface-version 'v1)
  
  (define timeout +inf.0)
  
 ; start : request -> response
  (define (start initial-request)
    `(html (head (title "A Test Page"))
           (body ([bgcolor "white"])
                 (p ,@(extract-bindings
                       'name
                       (request-bindings
initial-request))))))
