Defining channels in thing-types.xml?

Looking for a way to define 3 channels and give them each a different label.

Tried the following, which won’t compile.

	<channel id="r1" typeId="Robot" label="Robot #1" />
	<channel id="r2" typeId="Robot" label="Robot #2" />
	<channel id="r3" typeId="Robot" label="Robot #3" />
