The <productname>PostgreSQL</productname> distribution includes a

parsed DTD definitions file <filename>reference.ced</filename>.

You might find that when using <productname>PSGML</productname>, a

comfortable way of working with these separate files of book

parts is to insert a proper <literal>DOCTYPE</literal>

<productname>PSGML</productname>, but it's less confusing and

lighter weight. Also, it offers syntax highlighting (font lock),

which can be very helpful.

<filename>src/tools/editors/emacs.samples</filename> contains

sample settings for this mode.
