Protected Configuration: useMachineContainer's default value?

Question

In ASP.NET, when I'm using Protected Configuration, I'll specify something similar to the following in my web.config:

<configuration>
  <configProtectedData defaultProvider="SampleProvider">
    <providers>
      <add name="SampleProvider" 
        type="System.Configuration.RsaProtectedConfigurationProvider, 
              System.Configuration, Version=2.0.0.0, Culture=neutral, 
              PublicKeyToken=b03f5f7f11d50a3a,
             processorArchitecture=MSIL"
        keyContainerName="SampleKeys" 
        useMachineContainer="true" />
    </providers>
  </configProtectedData>
</configuration>

If I don't include it, what is the default value of the "useMachineContainer" attribute?
