I had a look :-)

Oddly, although I mention loading a DTD from a flattened version in
Near&Far (p.173) I don't say anything about using Near&Far to do the
actual flattening. Debbie is well ahead of me here.

On p.177, the book says:

I have snipped out those pages at
http://xml.silmaril.ie/downloads/normdtd-spam.pdf

The ospam binary is still shipped in the OpenSP package.

NormDTD was DOS-only
(https://nl.ijs.si/et/talks/Eurolan/silSGMLpubSWedit.html#normdtd)which
presumably means it will be happy in a modern DOS emulator.

I do still have the CD-ROM is anyone wants a copy.

You will still be able to install Win95 and then install NFD in it :-)
Meanwhile there is still a small market for a good schema visualiser of
the calibre of Near&Far. Nothing currently available comes anywhere near
IMNSHO.
