That would appear to have been taken from the "purchase" section of a template file rather than the rules definition. The purchase section essentially defines the default/starting purchases for any character based off of that template. Characteristic levels, Powers, Skills, etc. The rules definition area is what you're after.
In particular, you're missing the cost definitions for the Characteristic (how many points per level), the other Characteristics that it affects or is affected by, and the Display value.
Your best bet is to use one of the Characteristics that is the closest match for the mechanics of your new Characteristic as an example, replacing the container name, the XMLID, etc. You'll find the definitions in Main.hdt and/or Main6E.hdt, depending on which version of the rules you're working off of.
