It could be used by sysfs interface and string parsing, and I added some examples ahead of id and loop attributes, but for the patterns yes, it should be. As I have already added some comment before for the first comment from Dmitry, now the upload effect covers this attributes, so I would like to remove them and I have added some code a little bit more in the upload effect function in the next patch.

Thanks for your comments.
