Variables, Comments, and Character Entities

WML Variables
WML variable names in WML are prefixed with a dollar sign. The syntax is: 
   $variablename
If the end of the variable is not indicated by white space, you must contain the variable inside a pair of parentheses: 
   $(variablename)
The name of the variable can be composed of one or more uppercase or lowercase letters, digits, or underscores. 
   ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789_
Variable names are case sensitive. Variables can be assigned a value by using either the <setvar> or <postfield> elements. The value assigned to a variable can be substituted (displayed) in the text of a card.

WML comments may be placed anywhere in a WML deck. They will not appear in the display. Place the comments inside the following symbols: 
   <!-- Put the comments here. -->
