What does it mean to make clauses suggested by Contract Expert mandatory in a contract terms template?

When contract authors run Contract Expert on a contract, Contract Expert displays a list of any clauses that it recommends for insertion.

Contract authors can review the Contract Expert recommendations before the clauses get inserted into the contract. By setting the Expert Clauses Mandatory option when creating a contract terms template, you can specify if you want the clause insertion to be mandatory or if the authors can ignore the recommendations.

If you make the insertion mandatory, then only contract authors with the Override Contract Terms and Conditions Controls privilege, a special privilege that allows deleting mandatory clauses from the contract, can reject the recommendations. Similarly, if the recommended clauses are standard clauses, then the authors must have the Author Additional Standard Contract Terms and Conditions privilege to reject the recommendations. This privilege allows the deletion of standard clauses from the contract.
