I vaguely recall being able to use package:// to access files in packages, but I can't find the documentation and it turns out to be the kind of thing that is impossible to search for.
Can you actually access files in this manner? Is there a Wiki page about how to do it?
I think you're looking for this wiki page.
Not a general answer, but camera_info_manager supports that syntax for accessing camera calibration files. I suppose other packages do, too.
You can also use the "package://" syntax in URDF files, where a filename is required.
For example, the file
pr2_description/urdf/tilting_laser_v0/tilting_laser.urdf.xacro
contains the line:
<mesh filename="package://pr2_description/meshes/tilting_laser_v0/tilting_hokuyo.dae" />
This also works for the texture tag, which also needs a filename. I guess that internally, the resource_retriever package mentioned by Patrick is used. However, I cannot find any documentation on this.
