Accessor objects are mainly used to set or get values for data presented on a form, but they also allow getting or setting properties or rules related to the data attributes.

Get and Set Data Attribute Rules and Properties

The following are methods of Data Accessor Object objects:

event.<dataObject>.setAttributeRequiredRule('attributeCode', ruleKey, value)
event.<dataObject>.setAttributeAccessRule('attributeCode', ruleKey, value)
event.<dataObject>.setNativeAttributeRequiredRule('attributeCode', ruleKey, value)
event.<dataObject>.setNativeAttributeRequiredRule('attributeCode', ruleKey, value)
event.<dataObject>.setAttributeProperty('attributeCode', key, value)
event.<dataObject>.setNativeAttributeProperty('attributeCode', key, value)

Meaning of attribute properties or rules depend on Form Type. For example, some Form Types might not support any rules or properties at all.
