Use an Iterator to perform document instancing before creating content within the Body. The iterator resides directly before the Instance element. The document level iterator contains business logic and a corresponding PTR. The document level iterator determines how the rules are written for the entire document.
Each instance signifies a separate document for a transaction. For example, a document may be required for each borrower on the loan.
Instances: The container for all of the instances.
Instance: The container for a specific version of the printed document.
InstanceFormattingMetadata: When a new REQ file is created, the base InstanceFormattingMetadata is blank. The InstanceFormattingMetadata can be changed if there is a business need. The stylesheet will apply standard formatting. Elements under InstanceFormattingMetadata only need to be entered in the .REQ if it needs to override the defaults in the stylesheet. To override the available elements, right mouse click on the InstanceFormattingMetadata element and add the needed elements and their values.
InstanceDocumentRef: Contains content referenced from a specific schema (for example: ExpereDoc)

Document: The Document element is a container for content of the document (everything except the instancing and formatting metadata. Its children typically include the Tagline, Metadata, Prolog and Body.
