What does the term 'can' express in API standards?

The term 'can' in API standards is used to denote a statement of possibility or capability. This implies that when 'can' is used, it indicates that a particular action or behavior is feasible within the specified context of the API. It provides flexibility, suggesting that while the action is allowed or possible, it may not be required or mandatory.

For instance, in API documentation, when something is described as being able to be done using 'can', it suggests that developers have the option to implement that functionality if they choose to do so. This means they are capable of using specific features as per their needs or requirements but are not obligated to do so.

The other terms present in the question have distinct meanings and implications in the context of standards. Mandatory requirements refer to actions that must be followed strictly, hypothetical possibilities indicate outcomes that may occur under specific conditions, and judgments pertain to prescriptive recommendations of how things should be done. In contrast, 'can' specifically aligns with the idea of possibility and capability, establishing a clear understanding of the optional use of features in API standards.
