	For the purposes of this documentation the variable ``arch`` will be used in the following context ::

		>>> from binaryninja import *
		>>> arch = Architecture['x86']

	.. note:: The `max_instr_length` property of an architecture is not necessarily representative of the maximum instruction size of the associated CPU architecture. Rather, it represents the maximum size of a potential instruction that the architecture plugin can handle. So for example, the value for x86 is 16 despite the largest valid instruction being only 15 bytes long, and the value for mips32 is currently 8 because multiple instructions are decoded looking for delay slots so they can be reordered.

	``class InstructionTextToken`` is used to tell the core about the various components in the disassembly views.

	The below table is provided for documentation 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. UI plugins, however, may make use of them as appropriate.

	Uses of tokens include plugins that parse the output of an architecture (though parsing IL is recommended), or additionally, applying color schemes appropriately.
