The "include" files had type "book" for some raeason. I don't think this is meaningful. Let's just use the same everywhere. $ perl -i -0pe 's^..DOCTYPE (book|refentry) PUBLIC "-//OASIS//DTD DocBook XML V4.[25]//EN"\s+"http^<!DOCTYPE refentry PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"\n "http^gms' man/*.xml

<para>On success, <function>udev_device_get_is_initialized()</function> returns either <constant>1</constant> or

failure, a negative error code is returned. Note that devices for which no udev rules are defined are never

reported initialized.</para>
