DynamicAttributes (Java EE 5)

声明接受动态属性的标记必须实现此接口。还必须配置标记库描述符中该标记的条目，以指示接受动态属性。
对于此标记的标记库描述符中未声明的任何属性，将使用该属性的名称和值调用 setDynamicAttribute() 方法，而不是在转换期间出现错误。由标记负责记住动态属性的名称和值。

since

2.0

英文文档：

For a tag to declare that it accepts dynamic attributes, it must implement this interface. The entry for the tag in the Tag Library Descriptor must also be configured to indicate dynamic attributes are accepted.
For any attribute that is not declared in the Tag Library Descriptor for this tag, instead of getting an error at translation time, the setDynamicAttribute() method is called, with the name and value of the attribute. It is the responsibility of the tag to remember the names and values of the dynamic attributes.

Since:

JSP 2.0
