When creating Structured DataTypes, each field of a structure must have a unique name (as defined in the base OPC UA specification). The naming convention is to use PascalCase for those names. Examples: Offset, DaylightSavingInOffset

Note: In many Companion Specifications, and in the base OPC UA specifications, lower camel case (e.g. first word starts with a lower character) is used in the specification. However, the UaNodeSet uses PascalCase, and thus the OPC UA Server provides everything as PascalCase.
