+			 * This record is used to allow determining Firmware and CPLD revisions for
+			 * components in the system. The goal of this record is to provide a
+			 * flexible method to communicate to software and firmware the revisions
+			 * of these components. This record replaces much of the functionality of
+			 * Record Type 193. OEM SMBIOS Record Type 193 was not scaling well with
+			 * the large number of potential CPLD devices, power management controllers,
+			 * etc. This record is flexible such that each instance of Type 216
+			 * defines one firmware component. This record also includes the string
+			 * name for which software should refer to the component. The record
+			 * includes both data bytes to indicate the revision and a string value. A
+			 * firmware component can implement either or both. If both are supported,
+			 * it allows easy display of the revision, but prevents the need for
+			 * software/firmware to parse strings when doing comparisons on revisions.
+			 * As there is one Type 216 Record per firmware component, the Handle for
+			 * the Record can be used to tie firmware components with other OEM SMBIOS
+			 * Records in the future if needed (similar to how SMBIOS Type 17 is tied
+			 * to other Record Types related to DIMMs)
