NotationNone

"NotationNone" typically indicates the absence of any specific notation or symbol designated for a particular purpose within a given context. Essentially, it means that no special symbol, abbreviation, or representation has been assigned or is applicable. It is often used in technical, mathematical, or programming documents to clarify that no notation is used or needed for a certain item. This helps eliminate ambiguity by explicitly stating that nothing more needs to be represented or indicated in that instance.
