Avoid Invalid <param> tag: Unknown type 'yaml' in roslaunch examples

[liesrock]

I found some documentation here: http://wiki.ros.org/roslaunch/XML/param

Using mon launch everything works good.

Yes, roslaunch does not support the full XML specification provided (at least in kinetics). Meanwhile, users can use the tag rosparam to replace the param tag, i.e.

<param name="params_a" type="yaml" value="[1, 2, 3]" />

becomes

<rosparam name="params_a">
    [1, 2, 3]
</rosparam>

I also recommend to use the rosmon launcher :)
