DocBook extensions
Table of Contents
PhD has been tailored for PHP and PEAR manuals. To make writing documentation as easy as possible, some own tags have been added to the DTD.
All extensions live in their own XML namespace
"phd:" which resolves to
http://www.php.net/ns/phd. When using one of the attributes or
tags described here, remember to set the namespace:
xmlns:phd="http://www.php.net/ns/phd"
