The <plan> element has two attributes:
jarPath – The location of the plan XML, relative to the root of the bundle jar. 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, in Sun N1 Service Provisioning System 5.2 XML Schema Reference Guide for more information.
majorVersion – An optional attribute that determines whether to check in the plan as a new major version. The default is false.
