[DFDL-WG] dfdl-wg Digest, Vol 41, Issue 8

[Tim Kimber]

My understanding was different from what is quoted below. 'delimited' can 
always be terminated by the end of the data or the end of an enclosing 
known-length element. Without that rule, the simplest scenario involving 
an infix delimiter will not work correctly ( or will force the user to set 
lengthKind='endOfParent' on the final group member, which would be very 
unintuitive ).

There is a difference between endOfParent and delimited though. Delimited 
is not allowed when representation='binary'. 'endOfParent' is.

[DFDL-WG] dfdl:lentgKind= 'delimited' and 'endOfParent'


Since we extended the meaning of dfdl:lengthKind= 'delimited' to include 

'delimited' means the item is delimited by the item’s terminator (if 
specified) or an enclosing construct’s separator or the end of the 
enclosing construct designated by its known length or its terminator. 

 the only difference with dfdl:lentghKind='endOfParent' is that  the 
latter includes the 'end of the data stream'. 

We should either 
Add 'end of data stream' to delimited and remove 'endOfParent' 
Make 'endOfParent' be specifically for only  'end of data stream'
