* **`ID_STR_HEAPMIN` (0x6)**
Specifies the the ***minimum*** Java heap size (i.e. JVM option `-Xms`), as percentage of the total physical memory.
This must be an integral value in the `1` to `100` range, and it must be less than or equal to `ID_STR_HEAPMAX`.
This value must be an integral value in the `1` to `100` range.
(This option **must** be specified together with `ID_STR_HEAPMAX`)
(If `ID_STR_HEAPMAX` is specified too, then this value **must** be less than or equal to `ID_STR_HEAPMAX`).
* **`ID_STR_HEAPMAX` (0x7)**
Specifies the the ***maximum*** Java heap size (i.e. JVM option `-Xmx`), as percentage of the total physical memory.
This must be an integral value in the `1` to `100` range, and it must be greater than or equal to `ID_STR_HEAPMIN`.

Specifies the ***minimum*** supported JRE version, in the **`w.x.y.z`** format (e.g. `11.0.0.0`).
