A sample CRS XML v3.0 file, and how it validates

This is a CRS XML Schema v3.0 file produced by AEOIkit 1.5, with fictitious data. Validated against the official OECD CrsXML_v3.0.xsd on 23 October 2026, it gave zero errors and zero warnings. Download it and check it with any XSD validator.

What is in it

• A Cayman reporting FI (Test Fund Ltd, FI000123) sending a new-data message (CRS701) to one receiving jurisdiction.
• 4 account reports: individual and entity account holders, controlling persons, a joint account with its holder count, an equity-interest role, self-certification status and four payment types.
• MessageRefId and DocRefIds generated to the DITC conventions.
• All names, numbers and addresses are fictitious test data; any resemblance to a real FI, company or person is coincidental. The reporting period (2025) and the timestamp (20 July 2026) are fixed in our test fixture; a 2026 return has the same structure.

The validation result

Check it yourself

Download the OECD schema files from the OECD’s Tax Transparency Resource Centre, which the DITC points filers to (DITC Industry Advisory, 17 June 2026). Then run any XSD validator. For example, with xmllint:

xmllint --noout --schema CrsXML_v3.0.xsd aeoikit-sample-crs-v3.0.xml

What a schema check does not prove

The XSD checks structure. It does not check rules that compare fields with each other or with earlier filings, which is why AEOIkit also checks business rules before it builds a file. More on that in validation against CrsXML_v3.0.xsd. Passing the OECD schema is a test we run, not a certification, and AEOIkit is not endorsed by the DITC, CIMA or the OECD.
