A toggle with a Value writes it to its variable while on and nothing while off; its Negative goes with the variable. $name.bool reads the switch (true/false) across nodes, in text and in conditions, through __wp_toggle_bools__. Payloads reading $name.bool stamp schema 12; bool is reserved as a tag group.
