In the validation steps for various operations (for instance Batch Norm), the following dependencies/references/algorithms need to be defined (this entry will be kept updated):

• Internal slots for MLOperand:
  • [[type]] as MLOperandType
  • [[dimensions]] as sequence<unsigned long>
  • [[name]] as string (only for input operands)
  • [[data]] as ArrayBufferView (tensor of given dimensions)
  • [[builder]] the associated MLGraphBuilder
• Algorithm (or internal slot) to get the rank of the operand (for checking range for axis)
• Algorithm to internally create an MLOperand given |builder| and |descriptor|, used by op algorithms.
• Algorithm to internally copy an MLOperand, used by op algorithms.
• Algorithm to check dimensions given |dimensions| and |type|.
• Internal slots for MLActivation:
  • [[name]] as string, e.g. "relu", "sigmoid", "softmax", etc.
  • ? [[input]] as MLOperand (needed?)
  • ? [[output]] as MLOperand (intermediate output?)
• Algorithm to create an MLActivation, used by the op algorithms.
