Thorsten, a quick question...
The first part of my book build script has this:
echo "Validating book..."
if ! xmllint --xinclude --noout --postvalid book.xml
then
echo "Validation failed. Exiting."
exit 1
fi
echo "Complete."
Why did the book pass validation when using emdash entity reference? It
seems like that should have failed.
An example of the build script can be found at
https://github.com/noloader/POWER8-crypto/tree/master/docbook. make-
book.sh builds the book, and it includes the snippet.

Title:
xmllint does not recognize emdash (—)
Status in libxml2 package in Ubuntu:
Invalid
Bug description:
I'm using Ubuntu 20.04.2 LTS, x85_64, fully patched. 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...

Complete.
The text is:

email — do not require...</para>
It seems like emdash should be recognized.
