#1

You cannot use this parameter for applications in the archive format, because the files in the archive format cannot be modified. You can, however, use this parameter for applications in the exploded archive format.

#2

Although no warning message is output if you do not specify forward slash (/) at the beginning of an ID string, you cannot save the entire state. You can save only the partial state. We therefore recommend that you start a string with a forward slash (/).

#3
