Treat the statement as the front page of an evidence pack, not as the evidence pack itself. Each claim should link back to a test record, design decision, remediation ticket, procurement response, or operator assessment. If the statement says voice interaction has a non voice alternative, you should be able to point to the tested feature and the result.
For products, align the public or customer facing statement with Annex IV technical documentation and the EU declaration of conformity so that different teams are not publishing conflicting compliance claims. For services, align the statement with internal release gates and customer support procedures so that known issues and workarounds are not hidden.
