	// ResourceVariableKindStatic represents a static variable. Static variables
	// are resolved at the beginning of the execution and their value is constant.
	// Static variables are easy to find, they always start with 'spec'. Referring
	// to the instance spec.
	//
	// For example:
	//   spec:
	//      replicas: ${schema.spec.replicas + 5}
	ResourceVariableKindStatic ResourceVariableKind = "static"
	// ResourceVariableKindDynamic represents a dynamic variable. Dynamic variables
	// are resolved at runtime and their value can change during the execution. Dynamic
	// cannot start with 'spec' and they must refer to another resource in the
	// ResourceGraphDefinition.
	//
	// For example:
	//    spec:
	//	    vpcID: ${vpc.status.vpcID}
	ResourceVariableKindDynamic ResourceVariableKind = "dynamic"
	// ResourceVariableKindReadyWhen represents readyWhen variables. ReadyWhen variables
	// are resolved at runtime. The difference between them, and the dynamic variables
	// is that dynamic variable resolutions wait for other resources to provide a value
	// while ReadyWhen variables are created and wait for certain conditions before
	// moving forward to the next resource to create
	//
	// For example:
	//   name: cluster
	//   readyWhen:
	//   - ${cluster.status.status == "Active"}
	ResourceVariableKindReadyWhen ResourceVariableKind = "readyWhen"
	// ResourceVariableKindIncludeWhen represents an includeWhen variable.
	// IncludeWhen variables are resolved at the beginning of the execution and
	// their value is constant. They decide whether we are going to create
	// a resource or not
	//
	// For example:
	//   name: deployment
	//   includeWhen:
	//   - ${schema.spec.replicas > 1}
	ResourceVariableKindIncludeWhen ResourceVariableKind = "includeWhen"
	// ResourceVariableKindIteration represents an iteration variable. Iteration
	// variables are expressions inside a collection resource (one with forEach)
	// that reference iterator variables. They are evaluated during collection
	// expansion, once per iteration, with the iterator bindings in scope.
	//
	// For example, with forEach: [{region: "${schema.spec.regions}"}]:
	//   metadata:
	//     name: ${schema.spec.name}-${region}  <- "region" is an iterator variable
	//
	// Expressions not referencing iterator variables remain static or dynamic.
