Hi.. can I know how I use this kind of pointcut? an example maybe?

Maybe this is a silly question.. but this are the only description about attribute driven pointcut, and I dont understand:

5.2.3.1.2. Attribute-driven pointcuts
An important type of static pointcut is a metadata-driven pointcut. This uses the values of metadata attributes: typically, source-level metadata.
and also I found this in the reference:

Later versions of Spring may offer support for "semantic pointcuts" as offered by JAC: for example, "all methods that change instance variables in the target object."
is it already available in the latest version? and do you have any examples on using it?
