| * Global Notes: |
| * |
| * October 2005: The following list terms have been optimized (from the |
| * original ASL grammar in the ACPI specification) to force the immediate |
| * reduction of each list item so that the parse stack use doesn't increase on |
| * each list element and possibly overflow on very large lists (>4000 items). |
| * This dramatically reduces use of the parse stack overall. |
