body: <p>Given i have this example template:</p>
  
  <pre><code>{
      "AWSTemplateFormatVersion" : "2010-09-09",
      "Mappings" : {
          "RegionMap" : {
              "us-west-1" : { "AMI" : "ami-655a0a20" },
              ...
          }
      },
      "Resources" : {
          "Ec2Instance" : {
              "Type" : "AWS::EC2::Instance",
              "Properties" : {
                  ...
              },
              "DependsOn" : "myDB"
          },
          "myDB" : {
              "Type" : "AWS::RDS::DBInstance",
              "Properties" : {
                 ...
              }
          },
          "myDB2" : {
              "Type" : "AWS::RDS::DBInstance",
              "Properties" : {
                 ...
              }
          }
      }
  }
  </code></pre>
  
  <p>Is it possible to specify multiple DependsOn in any way?
  Would be great to have somethink like: </p>
  
  <pre><code>"DependsOn" : ["myDB", "myDB2"]
  </code></pre>
  
  <p>Whats the normal way?</p>
