What is the auto child name for a SelectItem's displayed value field?

I see auto child info for the picklist and icon in the APIs but not the value display field (div tag in HTML - a canvas?) of a SelectItem. I have to apply a custom attribute to that HTML element for only a single SelectItem instance (<div xxx="yyy") so a 3rd party API can snag its value.

Thanks!
