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

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.

Thoughts?
