Comments have no effect on the machine processable interpretation of an expression constraint, as they should be ignored during evaluation. For example, the following two expression constraints (the first with comments, and the second without), will evaluate to exactly the same set of concepts:

   /* Disorders of lung with edema */
   < 19829001 |Disorder of lung|: /* Descendants of disorder of lung */
         116676008 |Associated morphology| = << 79654002 |Edema|
         /* Where the associated morphology is edema or a subtype */

   < 19829001 |Disorder of lung|: 
         116676008 |Associated morphology| = << 79654002 |Edema|

A comment may include both stars and forward slashes. However a star may never be directly followed by a forward slash within the middle of a comment, as this combination denotes the end of the comment.
