- *
- * The attributes are a comma separated list of these possible
- * attributes:
- *
- *   + ro   - read-only
- *   + boot - boot-services access
- *   + run  - runtime access
- *
- * NOTE: with current implementation, no variables are available after
- * ExitBootServices, and all are persisted (if possible).
- *
- * If not specified, the attributes default to "{boot}".
- *
- * The required type is one of:
- *
- *   + utf8 - raw utf8 string
- *   + blob - arbitrary length hex string
- *
- * Maybe a utf16 type would be useful to for a string value to be auto
- * converted to utf16?
