I propose to apply the attached patch (to master) to update the DocBook
version to 4.5 (from 4.2). This basically just gets us off some random
intermediate minor version to the latest within that major version.
Most packagings put all 4.* versions into one package, so you probably
don't need to change anything in your tools. The exception is MacPorts,
as seen in the patch. (DocBook 4.5 was released in 2006, so it should
be available everywhere.)
