Confused about ItemTypes in thing-types.xml

Add-ons Bindings
1

Hey folks,
I’m currently developing my first binding to control PjLink compatible projectors.
In the pjlink protocol inputs are described by numbers e.g. HDMI=31, VGA=21 …

I used number as type:

<channel-type id="input" >
        <item-type>Number</item-type>
        <label>Input</label>
        <description>Input of the projector</description>
</channel-type>

Is there an nice way to configure the human readable input names for the user? Because it would be nicer to show the real names of the inputs.

I’m also new to binding development, but as far as I have seen you can use options under state.

<channel-type ...>
...
<state>
<options>
<option value="31">HDMI</option>
...
</options>
</state>
</channel-type>

But I don’t know if this is really shown in the UI or if this works together with the item-type Number.
