title: How do I add comment lines to a business rule authored in Business Action Language
body: <p>I am using JRules to author business rules. I want to add comments to the rules as shown in the very simple example below. I realise there is a documentation section for the rule but that is not what I require</p>
  
  <pre><code>// comments needed here
  
  definitions 
  set 'an existing customer' to a customer
  where the category of 'an existing customer' is "gold"
  
  if 
  the city of 'an existing customer' is "London"
  
  then
  give a 5% discount to 'an existing customer'
  
  else
  // and more comments needed here
  give a 10% discount to 'an existing customer'
  </code></pre>
  
  <p>Clearly, using the usual c++ and c# double forwardslash // will not work in the example above, so my question is how are comments added to rules in BAL.</p>
