* Removed trailing whitespace and blank lines.
* Needed to pass the GPG checks which are written for code.
* DocBook was valid without this step, but could not be committed
regardless. OTOH, it did remove 8KB from the file so not a total
waste.
* Would have been painful except I already have a function in
oXygenXML Editor to open a current file in Emacs and it did the work
here. :)
* DocBook 5.0 documentation for gpgmekeys.xsd.
* Documentation and images generated with oXygenXML Editor 17.1.
* DocBook to HTML conversion to follow.
