* Notes:
* <ul>
* <li>Invalid attributes are reported as errors.</li>
* <li><b>readwrite</b>, <b>strong</b>, and <b>atomic</b> attributes are removed
* since they are defaults.</li>
* <li>Strings will include the <b>copy</b> attribute.</li>
* </ul>
* <p>
* Example:
* <pre>
* class Foo {
* @Property("copy, nonatomic") protected String bar;
* }</pre>
* generates:
* <p>
* <pre>
* @property (copy, nonatomic) NSString *bar;</pre>
