For example, the following Entitlement time License Model attribute needs to be added to the Entitlement email. 

Add the following code after ActivationID: [[ActivationID]] under [[FOR-EACH TAG="EntitlementLineItem"]] line in text content or in HTML content and then validate and save the Entitlement Template

[[FOR-EACH TAG="EntitlementTimeLicenseModelAttributes"]]
[[FOR-EACH TAG="Attribute"]]
[[Name]] : [[Value]]
