casr.001.001.01

Q: How do I validate a casr.001 message?

Run askiso validate message.xml . The schema is found from the document's own namespace, so you do not name it. Validation needs that schema installed. To check the business rules without one, run askiso lint instead.

What casr.001.001.01 is

casr.001.001.01 is an ISO 20022 message definition. Its business area is CASR (casr), and casr.001 is the definition it versions.

AskISO does not copy the specification. The Registration Authority publishes the message definition report and the schema, free of charge. The links below go straight there.

This is one of 3 published versions of casr.001, and it is not the newest. The current version is casr.001.001.03. That does not make this page obsolete: a counterparty running an older integration may still send you exactly this version, and you will need to read it.

Versions of casr.001

The standard publishes 3 versions of this definition. A newer version does not automatically replace an older one. The scheme or market infrastructure you send to decides which version you should be using.
