// TagResourceRequest returns a request value for making API operation for
// Amazon CloudWatch Events.
//
// Assigns one or more tags (key-value pairs) to the specified EventBridge resource.
// Tags can help you organize and categorize your resources. You can also use
// them to scope user permissions by granting a user permission to access or
// change only resources with certain tag values. In EventBridge, rules and
// event buses can be tagged.
//
// Tags don't have any semantic meaning to AWS and are interpreted strictly
// as strings of characters.
//
// You can use the TagResource action with a resource that already has tags.
// If you specify a new tag key, this tag is appended to the list of tags associated
// with the resource. If you specify a tag key that is already associated with
// the resource, the new tag value that you specify replaces the previous value
// for that tag.
//
// You can associate as many as 50 tags with a resource.
//
