IBM DFDL also allows this, as spec section 12.3.2 says: The data stream is scanned for any of - the element's terminator (if specified) - an enclosing construct's separator or terminator - the end of an enclosing element designated by its known length - the end of the data stream Regards Steve Hanson IBM Hybrid Integration, Hursley, UK Architect, IBM DFDL Co-Chair, OGF DFDL Working Group smh@uk.ibm.com tel:+44-1962-815848 mob:+44-7717-378890 Note: I work Tuesday to Friday From: "Mike Beckerle" <mbeckerle@apache.org> To: "DFDL-WG" <dfdl-wg@ogf.org> Date: 25/01/2022 17:36 Subject: [EXTERNAL] [DFDL-WG] clarification: lengthKind 'delimited' but no terminating delimiter in scope Sent by: "dfdl-wg" <dfdl-wg-bounces@ogf.org> Is this an SDE? Or allowed? Daffodil currently implements this as allowed, and it ends up behaving much like "endOfParent", i.e., a scan for delimiters, when none are specified, scans as far as it can. However, given that we have endOfParent to express this behavior, seems to me that delimited with no delimiter should be an SDE.
