Notification templates and events use a unique syntax for notification structure. This syntax is case sensitive, but allows sending data to the notification engine. Parameters sent alongside the event help change the structure of the notification.
There are two types of markup properties available for use within a message template:
1. Placeholders: binds values passed in by the notification request to the template. Placeholders may display text when outputted.
2. Tags: used to manipulate how a message appears. Tags never display text when outputted.
Both the placeholder and block properties provide users with complete control over their notifications.
Users wishing to alter HTML structure should surround the advanced syntax language with comments.
