Fedwire — header announces a different message than it carries

The Business Application Header says <MsgDefIdr>pacs.009.001.08</MsgDefIdr> while the document it heads is a pacs.008. Both halves validate against their own schema; only comparing them catches it.

How we know these results hold

Every file in this library is run through the site's own validator on each build. The expected result stated above is asserted by an automated test — if a file stopped matching what this page claims, the build would fail. Two inherited fixtures were repaired this way before publication: three IBANs failed the mod-97 check and several names used characters outside the basic SEPA character set.
