So which is worse, Steve, a bunch of extra properties in GeneralPurposeFormat, or making your schema designers resort to workarounds like this: <xs:sequence dfdl:separator="" dfdl:terminator="end" dfdl:ignoreCase="no"> <xs:element name="weird" type="xs:string" dfdl:initiator="start" dfdl:ignoreCase="yes" dfdl:lengthKind="delimited"/> </xs:sequence> Or this: - wrap the element in a group - set dfdl:ignoreCase to 'no' on the group. - set dfdl:ignoreCase to 'yes' on the element. - put the terminator on the group and the initiator on the element. Do you really want your schema designers to have to do things like this? It seems to me that a good design principle is to make life simpler for your users, not harder.

It's not just ignoreCase. There's encoding and its related properties too. We decided that encoding related properties applied per object, not per delimiter.

The only way I can think of dealing with this is to use the initiator, but handle the length via lengthKind='pattern' to grab the value, doing lookahead so it will stop before the terminator. Then an empty sequence with a case sensitive terminator to pick off that part of the data stream. -- Mike Beckerle | OGF DFDL Workgroup Co-Chair | Tresys Technology | www.tresys.com<http://www.tresys.com/> -- dfdl-wg mailing list dfdl-wg@ogf.org<mailto: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.
