Attribute Data Types

Vault components and subcomponents use attribute values for their configuration.

MDL attributes use the following data types:

Data Type	Description	Validation	Example
String	Can contain letters, numbers, and spaces.	Must be wrapped in single quotes ('). Maximum number of characters allowed is defined as max_length on the attribute metadata	attribute('This is a String')
Boolean	Can have two values: true and false		attribute(true)
Number	Contains digits.	Maximum value defined as max_value on the attribute metadata. Minimum value defined as min_value on the attribute metadata. Max number of decimal places defined as scale on the attribute metadata	attribute(1234)
Component	A reference to a component in the Vault.	Component type is defined as component on the attribute metadata	attribute('Doctype.my_special_doctype__c')
Enum	A value from a list of predefined values sorted in the order you entered them.	Allowed values list defined as enums on the attribute metadata	attribute('Red')
XMLString	Complex data in XML format	The specified values bust be wrapped in curly brackets ({}). The framework validates XML structure only (not the content).
