Unfortunately this may not be identical to the string used as the heap name (ie: "system" vs "system_heap"). This can cause some minor confusion with tooling, and there is the future potential where multiple heap types may be exported by the same module (but would all have the same name). So to avoid all this, set the exporter exp_name to the heap name.
