nXML "No completions available"
I am in my new-ish:
Linux debian.localdomain 4.9.0-9-amd64 #1 SMP Debian
4.9.168-1+deb9u3 (2019-06-16) x86_64 GNU/Linux
I seek to edit a DocBook XML file in emacs23. The file
<?xml version='1.0' ?>
<!DOCTYPE article PUBLIC "-//OASIS//DTD DocBook XML V4.4//EN"
Does that seem okay? However, trying out autocompletion
with Esc-TAB gives me the error message noted in my
Subject: "no completions available."
I created the small file many years ago and am able to use
xsltproc and an xsl style sheet to produce a suitable pdf.
Now I want to edit it. I remember virtually nothing of how
to actually _use_ nXML in emacs, that is, keystrokes.
(How, for example can I bring up a list of valid tags for
insertion at a given point in the file?)
Never ascribe to malice what can be explained by stupidity.
