 * Marks a method-targeting attribute as having parameters to parse.
 *
 * If a method attribute has this interface, then after it is created
 * the analyzer will check all parameters of the method for the attribute
 * returned by parameterAttribute().  If one is absent (once inheritance
 * and transtivity is taken into account), then it will be omitted if
 * includeParametersByDefault() is false, or will be created with no constructor
 * arguments if it returns true.  The whole list of resulting paraemter
 * attribute objects will be passed to the setParameters() method for
 * the method attribute to save and then use however it wishes.
 *
 * Note that it is an error if the parameter attribute has required
 * arguments, includeParametersByDefault() is true, and any property is missing
 * an attribute.
