ArgList

An ordered list of attributes whose values are passed to the open, close, online, offline, monitor, info, action, and clean entry points.

The default is an empty list. The ArgList attribute value cannot be overridden.

ArgList reference attributes

Reference attributes refer to attributes of a different resource. If the value of a resource's attribute is the name of another resource, the ArgList of the first resource can refer to an attribute of the second resource using the : operator.

For example, say, there is a type T1 whose ArgList is of the form:

{ Attr1, Attr2, Attr3:Attr_A }

where Attr1, Attr2 and Attr3 are attributes of type T1, and say for a resource res1T1 of type T1, Attr3 's value is the name of another resource, res1T2. Then the entry points for res1T1 are passed the values of attributes Attr1 and Attr2 of res1T1 and the value of attribute Attr_A of resource res1T2.

Note that one has to first add the attribute Attr3 to type T1 before adding Attr3:Attr_A to T1's ArgList. Only then should one modify Attr3 for a resource (res1T1) to reference another resource (res1T2). Also, the value of Attr3 can either be another resource of the same time (res2T1) or a resource of a different type (res1T2).
