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 begins: <?xml version='1.0' ?> <!DOCTYPE article PUBLIC "-//OASIS//DTD DocBook XML V4.4//EN" "/usr/share/sgml/docbook/dtd/xml/4.4/docbookx.dtd" []> 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?) Thank you -- Never ascribe to malice what can be explained by stupidity.
