About Transactions and Transaction Data
The business rules that govern the selection and assembly of documents are driven by data. This data is supplied to the selection and assembly facility as an XML document referred to as the transaction data. Transaction data may be supplemented with values that are common across many transactions. Common data values may be delivered with the transaction data or may be determined by a policy rules program that modifies the transaction data. Policy rules are driven by transaction characteristics, such as the applicable law state or the type of loan and can also insert data values unconditionally. The policy program is optional and can be ignored if all values are passed in the transaction data. When the data is used for document selection and assembly it must be in a single XML document and that document must be valid according to a transaction schema.
