Not sure why you would want to use a URI there - after all, all you need is a unique
name for the feature. So "find" or "pagenumber" might do the job.
It might also be simpler to just have
X-KDE-PageNumberParameter=<parameter name>
instead of having to iterate over all ExecParameters.
Note that KService makes it easy to query for custom properties. You might need to
define the property in kio/application.desktop in order to let KService know its type though.

Can't think of a way to do this already. It does sound pretty close to the
"TempFile" option support I added some time ago (cf PropertyDef::X-KDE-HasTempFileOption
in application.desktop, and the KCmdLineArgs method).
The idea there is the same: the app says in its .desktop file that it supports
a given option, although in the case of the tempfile option, the name of the
command-line option is actually fixed. Your solution is more flexible,
especially for .desktop files describing non-KDE applications.
