HasMultipleValues: Boolean;
The HasMultipleValues property determines if an attribute may have multiple values.
Use JSON or the setHasMultipleValues method to set the property value, and the getHasMultipleValues method to get the property value.
If this property is set to true the attribute may have multiple values, otherwise it may not (default).
The example of use is given on the page with description of the Attribute constructor.
