 	The below table is provided for ducmentation purposes but the complete list of TokenTypes is available at: :class:`!enums.InstructionTextTokenType`. Note that types marked as `Not emitted by architectures` are not intended to be used by Architectures during lifting. Rather, they are added by the core during analysis or display.
