This UID will uniquely identify the SIS file, except for the case of upgrades, where both SIS files will share the same UID3 This UID should be the same as the UID present in the SISUid SISField in the top level SISController. Note that this UID (UID3) is generally referred-to in other documentation as the package-UID, or pUID for short. 3.1.4 UID Checksum This field provides a checksum of the UID structure in its entirety. 4 SIS Fields 4.1 General SISFields 4.1.1 SISString This SISField contains a UCS-2 encoded Unicode string.

Its length in bytes is specified by the Length field, and since each character is encoded using 16 bits there will be half as many characters in the string, as specified by this length. 4.1.2 SISArray The SISArray SISField holds an array of one SISField type. The type of the contained SISFields will be checked on creation from data, and addition of each new SISField. The notation SISArray<SISString> will be used to indicate an array of SISStrings. All of the SISFields in the array are stored without their type as an optimisation, so just the length and value parts of the TLV are stored.
