I too have been trying to work through the differences between the documentation and what's implemented.
I've started working on a tutorial to guide people through how to make a complete model with the robot state publisher. Check it out here:
That said, I haven't finished writing it yet. And the documentation is unclear how to apply textures, so I haven't finished that part yet. But maybe you'll find it useful.

Hello ROS Community,
I would like to inform people who are in charge of the ROS Wiki that the
URDF/XML tutorial is not up to date. I noticed that the formalism is not
the same anymore: for instance, the tutorial does not mention the fact
that the tag <material> requires a name (<material name="blablabla">).
Another thing, the <color> tag does not work as shown on the tutorial
anymore: <color rgb="0 255 255" alpha="1.0"/> is not recognized when the
file is parsed, it has to be <color rgba="0.7 0.7 0.7 1.0"/>
Maybe an update of that tutorial would be nice !
About this new rgba notation: what are the figures used for the R, G and
B values ? They are not the 0-255 basic values for the RGB system, and I
cannot find what it is.
They belong to the [0, 1] interval.
HTH,
Adolfo
