initiatedContent = "yes" has two purposes, firstly it forces the model author to specify an initiator on all the children of a sequence; secondly the initiator is used to discriminate children that are a 'point of uncertainty'. An initiator expression is not able to return "no initiator" (see errata 2.63), so in that sense there is nothing different between a static initiator and a dynamic initiator. I don't see a need for initiatedContent = "yes" to distinguish between the two.

My question: I see no language prohibiting this, but ... can/should one use this in conjunction with an initiator expression (evaluated at runtime from data), or do we restrict and say that initiatedContent="yes" requires a static string literal for the initiator for all the children? ...mikeb -- Mike Beckerle | OGF DFDL WG Co-Chair Tel: 781-330-0412 -- dfdl-wg mailing list dfdl-wg@ogf.org https://www.ogf.org/mailman/listinfo/dfdl-wg Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
