Substitution Tokens

Substitution tokens can be used in a number of attribute string values when customizing events.

They can be used in the following attributes:

summary attribute when customizing the summary description for an event—see Customizing Event Descriptions.
detail attribute when customizing the detail description for an event—see Customizing Event Descriptions.
name attribute when customizing event links—see name Attribute.
query attribute when customizing pre-defined filters for event links and templates (see query Attribute), as well as query strings for defining sub-process links (see Sub-Process Links).
description attribute when customizing pre-defined filters —see description Attribute.
Substitution tokens that you include in these attributes are replaced with attribute values at runtime.

When included in an attribute, substitution tokens must be enclosed in { } braces (as well as single quotes in the query attribute). For example:
```
query="applicationActivityInstanceId='{ActivityID}' AND
       principalName='{sessionResourceName}'"
```
