[Psgml-user] Trouble with docbook dtd install

[Skinner, R. <Reed.Skinner@Eclipsys.com>]

Hi all,

I'm running emacs 20.7 on Win 98, no Cygwin tools.

I'm following the tutorial that Markus kindly wrote and I'm at a stumbling
block. Up to this point everything has since I decided to completely start
over. However, I'm at the point in the instructions of the NTSGML tutorial
where I am creating the dbtest.sgml as a sample docbook document. I inserted
the docbook41 dtd and when it parses it gives me the following error
message:

External entity BOOK not found
  Public identifier -//OASIS//DTD DocBook V4.1//EN

Then if I go to the end of that and start to insert elements, I can insert
the <book> element but after that it will not allow me to insert any other
elements. I keep getting a "No valid element at this point" message in the
mini-buffer. I figured that maybe I have installed the docbook, entities,
and stylesheets incorrectly but I I have followed the instructions exactly
several times and I still can't get past this. Any ideas on what I'm doing
wrong?

Thanks in advance,

Reed Skinner
