I think you are right - this is not a bug. I took a quick peek at RFC 3470, and I don't see where HTML entity references are optional. Sorry about that. I got some bad info off the internet (surprise, surprise). It said to use the character entity reference for emdash due to portability problems when using the character itself.

I'm using DocBook to build a PDF. One of the steps I use in my build script is to validate and format the XML using xmllint from libxml2-utils 2.9.13+dfsg-1ubuntu0.3: echo "Validating book..." if ! xmllint --xinclude --noout --postvalid book.xml then echo "Validation failed. Exiting." exit 1 fi echo "Complete." echo "Formatting source code..." for file in *.xml do if xmllint --format "${file}" --output "${file}.format" then mv "${file}.format" "${file}" fi done echo "Complete." When I added an emdash (—) the book failed to format: Validating book... Complete. Formatting source code... ch02.xml:58: parser error : Entity 'mdash' not defined injections are remediated using several methods. And two output devices — ^ ch02.xml:58: parser error : Entity 'mdash' not defined methods. And two output devices — the printer and plaintext email — ^ Complete. The text is: <para>...
