+     *                  can use a union type by providing an array of simple types. If one of the union types matches
+     *                  the provided value, then the value is valid.
+     * - instanceOf:    (string) When the type is an object, you can specify the class that the object must implement
+     * - required:      (bool) Whether or not the parameter is required
+     * - default:       (mixed) Default value to use if no value is supplied

+     * - description:   (string) Documentation of the parameter

+     *                  with a command, but the defaults are uri, query, header, body, json, xml, postField, postFile.
+     * - sentAs:        (string) Specifies how the data being modeled is sent over the wire. For example, you may wish
+     *                  to include certain headers in a response model that have a normalized casing of FooBar, but the
+     *                  actual header is x-foo-bar. In this case, sentAs would be set to x-foo-bar.
+     * - filters:       (array) Array of static method names to to run a parameter value through. Each value in the
+     *                  array must be a string containing the full class path to a static method or an array of complex
+     *                  filter information. You can specify static methods of classes using the full namespace class

+     *                  filter a value. For complex filters, use a hash containing a 'method' key pointing to a static
+     *                  method, and an 'args' key containing an array of positional arguments to pass to the method.
+     *                  Arguments can contain keywords that are replaced when filtering a value: '@value' is replaced
+     *                  with the value being validated, '@api' is replaced with the Parameter object.
+     * - properties:    When the type is an object, you can specify nested parameters
+     * - additionalProperties: (array) This attribute defines a schema for all properties that are not explicitly
+     *                  defined in an object type definition. If specified, the value MUST be a schema or a boolean. If
+     *                  false is provided, no additional properties are allowed beyond the properties defined in the
+     *                  schema. The default value is an empty schema which allows any value for additional properties.
+     * - items:         This attribute defines the allowed items in an instance array, and MUST be a schema or an array
+     *                  of schemas. The default value is an empty schema which allows any value for items in the
+     *                  instance array.
+     *                  When this attribute value is a schema and the instance value is an array, then all the items
+     *                  in the array MUST be valid according to the schema.
+     * - pattern:       When the type is a string, you can specify the regex pattern that a value must match
+     * - enum:          When the type is a string, you can specify a list of acceptable values
+     * - minItems:      (int) Minimum number of items allowed in an array
