Hi,

I am new to the command chain pattern and kindly bear with me if this
is a basic question.

In the catalog below,

<catalog>
  <chain main>
     <command 1/>
     <command 2 lookup(sub)/>
     <command 5/>
 </chain>

 <chain sub>
    <command 3>
    <command 4>
 </chain>

If command 3 were to return true, will command 5 execute ? Thanks.
