-- | The resource tags that Firewall Manager uses to determine if a
-- particular resource should be included or excluded from the Firewall
-- Manager policy. Tags enable you to categorize your Amazon Web Services
-- resources in different ways, for example, by purpose, owner, or
-- environment. Each tag consists of a key and an optional value. Firewall
-- Manager combines the tags with \"AND\" so that, if you add more than one
-- tag to a policy scope, a resource must have all the specified tags to be
-- included or excluded. For more information, see
-- <https://docs.aws.amazon.com/awsconsolehelpdocs/latest/gsg/tag-editor.html Working with Tag Editor>.
