Elegant. Thank you. From: Mike Beckerle [mailto:mbeckerle.dfdl@gmail.com] Sent: Wednesday, February 27, 2013 1:04 PM To: Garriss Jr., James P. Cc: dfdl-wg@ogf.org Subject: Re: [DFDL-WG] Alternate Initiators? dfdl:initiator="Message-ID Message-Id" i.e., it's a whitespace separated list of alternatives. There's also a property called dfdl:ignoreCase="yes", but that would allow "mEssAge-iD" as well, which you probably don't want.

In our DFDL schema, "Message-ID" is an initiator, but suddenly we have two alternate initiators for the same element. How we model this in DFDL?
