1. How do you parse the DTD?

2. Here's a variable declaration and some code I use in an sgml-mode-hook
   function:

(defvar psgml-auto-parse 'query
  "*If t, `\\[sgml-mode'] automatically invokes `\\[sgml-next-trouble-spot]';
if a number, automatically parse the buffer if the buffer's size is smaller;
if non-nil and non-t, query the user whether to parse the buffer.")

  (if (and (cond ((eq psgml-auto-parse t))
                 ((numberp psgml-auto-parse)
                  (<= (buffer-size) psgml-auto-parse))
                 ((not (null psgml-auto-parse)) ; symbolp
                  (y-or-n-p "Parse SGML document? ")))
           (or (null sgml-top-tree)
               (null (sgml-tree-end sgml-top-tree))))
      (progn
        (sgml-next-trouble-spot)        ; doesn't return a meaningful value,
                                        ; or signal an error...
        (if (eobp)
            (goto-char (point-min)))))
