-          MediaType supported for BOM artifact is 'application/xml' or 'application/json'.
+          The BOM artifact may be supplied uncompressed or compressed. If the BOM is uncompressed,
+          the supported MediaType is 'application/xml' or 'application/json'. If the BOM is compressed,
+          the supported MediaType is 'application/gzip' or 'application/zstd' and must match the actual
+          compression of the data.
           The BOM will be validated against the CycloneDX schema. If schema validation fails,
           a response with problem details in RFC 9457 format will be returned. In this case,
           the response's content type will be <code>application/problem+json</code>.
