— versions 4-7 were omitted to align with UmtsHI2Operations.

lastVersion(8)

— Mandatory parameter "version" (tag 1) was always redundant in 33.108, because

— the object identifier "hi3DomainId" was introduced into "ULIC-headerV in the initial

— version of 33.108v5.0.0 In order to keep backward compatibility, even when the

— version of the "hi3DomainId" parameter will be incremented it is recommended to

— always send to LEMF the same: enumeration value "lastVersion(8)".

— Country Code according to ISO 3166-1 [39],

— the country to which the parameters inserted after the extension marker apply

…

— In case a given country wants to use additional national parameters according to its law,

— these national parameters should be defined using the ASN.1 syntax and added after the

— extension marker (…).

— It is recommended that "version parameter" and "vendor identification parameter" are

— included in the national parameters definition. Vendor identifications can be

— retrieved from IANA web site. It is recommended to avoid

— using tags from 240 to 255 in a formal type definition.
