targetType

Specify a target type to define the kinds of resources the document can run on. For example, to run a document on EC2 instances, specify the following value: /AWS::EC2::Instance. If you specify a value of '/' the document can run on all types of resources. If you don't specify a value, the document can't run on any resources. For a list of valid resource types, see Amazon Web Services resource and property types reference in the CloudFormation User Guide.
