The NumericRange defines "A null string indicates that this parameter is not used."
Most server implementations treat null AND empty as "not used".

Added new chapter

4.3 Null Service parameters
Service parameters may be optional or omitting the parameter may have a special meaning. Such cases are defined in the paramter descriptions. The terms null, empty or omitted are used interchangeably in parameter descriptions.

Added in OPC 10000-4 - UA Specification Part 4 - Services 1.05.0 Draft12.docx

Search all null places for String and ByteString and make sure null and empty are used in all places where it makes sense.

Searched all null places for String, ByteString or array parameters and changed 'null' to 'null and empty' where empty was not included yet.

Changed in OPC 10000-4 - UA Specification Part 4 - Services 1.05.0 Draft13.docx
