Identifiers
Identifiers are the names of variables as used in the namespace. These identifiers must follow a predefined format as described in this section.
Variable names
A variable name is defined as letter (letter | digit)*
This means that a variable can begin with a letter, followed by multiple letters or digits.
Letters can be any of the following: A-Z, a-z, _, $, @. Numbers must be 0-9.
Example:
<#assign total_price_1 = unit_price_1 * quantity_1>
Variables with the same name but different case are considered different variables. For example, the following variables are different:
<#assign variable = Variable>
