Lines 38 to 56 in cb9e67b

	>**\_correct** (string): When the mandatory questions contained are all correct and complete, this is the id of the next content block.
	>**\_partlyCorrect** (string): When the mandatory questions contained are partly correct and complete, this is the id of the next content block.
	>**\_incorrect** (string): When the mandatory questions contained are all incorrect and complete, this is the id of the next content block.
	>**\_hasAttemptBands** (boolean): If set to `true`, turns on the **\_attemptBands** behaviour, allowing branching to happen across both attempts and correctness.
	>**\_useQuestionAttempts** (boolean): If set to `true`, **\_hasAttemptBands** will branch according to the previous completed attempts at this question.
	>**\_attemptBands** (object array): Multiple items may be created. Each item represents the branching options for the appropriate range of attempts. **\_attemptBands** contains values for **\_attempts**, **\_correct**, **\_partlyCorrect** and **\_incorrect**.
	>>**\_attempts** (number): This numeric value represents the start of the range. The range continues to the next highest **\_attempts** of another band.
	>>**\_correct** (string): When the mandatory questions contained are all correct and complete, this is the id of the next content block.
	>>**\_partlyCorrect** (string): When the mandatory questions contained are partly correct and complete, this is the id of the next content block.
	>>**\_incorrect** (string): When the mandatory questions contained are all incorrect and complete, this is the id of the next content block.

As it checks all questions, not just the mandatory ones.
