The <plan> element is a child of the <memberList> element and is used to declare a plan in the plug-in JAR. All objects referenced by this plan must have been previously defined either in this plug-in or in a plug-in on which this plug-in directly depends.
The <plan> element has two attributes:
jarPath – The location of the plan XML, relative to the root of the plug-in JAR file. Leading / or . characters are not permitted. The format of the plan XML is specified by the Plan and Component Language specification. See Chapter 4, Plan Schema for more information.
majorVersion – An optional attribute that determines whether to check in the plan as a new major version. The default is false.
