Abstract: A dynamic token system is described herein that allows the insertion of dynamic content into document templates that execute logic at run time to determine content to use to replace the token. A dynamic token is a generic mechanism to add content to a document body. Authors can implement a uniform defined interface, and reference a class containing custom software logic as a token in the document template. When a parser reaches that token, it invokes the dynamic token implementation, which has access to the entire payload and has the appropriate context to act accordingly. Each token can perform a very specific action, augment the payload if necessary, and output the desired information. This mechanism allows administrators to fulfill numerous requirements that are otherwise extremely complicated if not impossible. Thus, the system provides manageable, extensible document templates that can be applied to a wider variety of situations.
