I am not sure what a more accurate term would be. This represents the form field for this particular group and can be set explicitly via:

    <div alch-form-group field="name"></div>

The explicit setting is for cases where there isn't a single input or its not obvious what the field should be. If there is no field specified, the directive punts to using the input's ID. If you think this should be:

    <div alch-form-group input-id="name"></div>

I can change it. Just seemed less obvious to me.
