Mike A number of people at IBM have become concerned at the number of properties in DFDL and have identified a number of 'usability' properties that could be dropped. They feel that we should be simplifying the properties wherever possible and not introducing multiple ways of doing the same function without very good reason. The following are offered for consideration. lengthKind='nullterminated' This is just shorthand for lengthKind=delimited and terminator='%Null'. It was felt this this is not even the most common terminator so why have a special case? trimKind It is felt that there aren't any cases when you would want to pad but not trim and vice versa so make padKind control both. typeSubstitution. Is this needed in DFDL v1? Can you consider these before the call next week Alan Powell MP 211, IBM UK Labs, Hursley, Winchester, SO21 2JN, England Notes Id: Alan Powell/UK/IBM email: alan_powell@uk.ibm.com Tel: +44 (0)1962 815073 Fax: +44 (0)1962 816898 Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
