<TECH> I65 Repetition Separator
X12 4020 introduced the Repetition Separator (I65) to the standard
replacing the Interchange Control Standards Identifier (I10). I think
Rachael reported something about this earlier on in the old list.
I've had a quick look at the documentation but I couldn't find any
implementation information so I've a couple of questions...
First, has anyone seen any real-world use of this separator that they
can share? I'm not talking about just its presence in the ISA but
actually in use in data.
I couldn't see any definitions of repeating elements in the standards
(although I didn't look real hard) but its theoretical use seems to be a
bit ambiguous. For example, if I have a repeating composite element
which contains a repeating simple element and an optional simple
element, how do I know when the composite element changes to its next
instance rather than the simple element repeating?
Thanks for any insights.
Andy
