[DFDL-WG] clarification: lengthKind 'delimited' but no terminating delimiter in scope

[Steve Hanson]

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

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?
