allowEmptyValue is used in query, header, cookie and form parameters. This is its behaviour:

During validation, the ValidationHandler check if there's a parameter with combination of location and name
as defined in this rule 
If it not exists, It will check allowEmptyValue and if there's a default value set inside
ParameterTypeValidator:

If this condition it's true, It marks as validated the parameter and returns the default value (inside
RequestParameter)
If this condition it's false, It throws ValidationException

If the parameter exists, It checks if parameter is null or empty string:

If allowEmptyValue it's true, It marks as validated the parameter and returns the default value if it exists
(inside RequestParameter)
If allowEmptyValue it's false, It throws ValidationException


Returns:
