The makefile target to check the docbook manual is:
make doc-xml-validate-docbook

It should also be linked from doc/xml/manual/intro.xml so it appears
as part of the manual.

The first paragraph says the table is based on the table of contents
of the CD, but it isn't.  I agree with only showing the C++14 changes,
but the first paragraph should be changed (or removed.)
