London Market Implementation of ACORD DRI Messages and Data
This section should be read in conjunction with the London Market ACORD DRI Messages Completion and Validation Rules v1 Data completion and validation principles are detailed in the London Market Technical Information Section 4. Elements of that document are summarised below.
The following assumptions govern the XML Schema Architecture to be adopted:
The London Market will use the ACORD RLC and DRI Standard for XML Messaging as released and maintained by ACORD. It will not use a customised version of this standard.
Validation of message content will be undertaken at the XML Schema level wherever possible.
London Market rules will implement:
increased restrictions to elements and attributes defined in the ACORD Standard as defined in 1 above
It must be possible to send and receive messages compliant with the full ACORD Standard (not just messages that are limited to the London Market requirements).
XML standard definition and content validation will be undertaken at the XML Schema level, the XML parsing level (using a tool such as Schematron) and the application level. The order of precedence for validation is:
ACORD XML Schema
Conditional rules and restrictions defined and validated in an XML-based tool
Conditional rules and restrictions validated by the sender’s and/or receiver’s application
Code Sets are available as a central resource for all participants. Ideally these will be accessible as XML files. Validation against Code Sets may occur either within an XML Schema (if they are incorporated as enumerations), or within the XML-based validation tool, or within the sender’s or receiver’s application.
Reference code validation will be undertaken within the XML-based validation tool independent of sender/receiver application wherever possible.
The following are the basic capabilities of what may be defined within an XML Schema, and consequently what may be validated. All other specification requirements such as element and content conditionality will be defined and
