For example, 2.0 refers to the UEFI 2.0 Specification, and 1.02 refers to the EFI 1.02 Specification. If the entry in the table contains a value followed by a '+' such as 1.1+ or 2.1+, then that means the feature optionally applies to that category of UEFI Driver if the UEFI Driver is required to run correctly on platform firmware that conforms to the version of the EFI Specification or UEFI Specification specified by the value or higher values. For example, 2.0+ refers to the UEFI 2.0, 2.1, 2.2, 2.3, and 2.3.1 Specifications.
