Subject: RE: Re: Schema & BP Spec: Items for today's BP/CC meeting
Neal, Regarding W3C Schema and DTDs, we tried to be forward compatible wherever possible. For example timeToPerform, we chose to specify (via comment) that ISO 8601 should be used. W3C Schema datatype for duration is ISO 8601 with the proper "value space". Which means, an XML data stream could be validated by both a DTD and a Schema. ________________________________________________________________ Kurt Kanaskie Lucent Technologies kkanaskie@lucent.com (610) 778-1069 Note the new number! -----Original Message----- From: Smith, Neal L.

One might argue that DTD isn't really a schema specification and we ought to wait until W3C Schema is approved before proceding. I merely propose a practical approach of targeting ebXML toward the most current and comprehensive schema standard, while providing a DTD for compatibility with existing tools. This is not merely an academic argument. In the BP Specification DTD, "timeToPerform" is CDATA with a comment that "time periods are represented using ISO8601 format". In W3C Schema, timeToPerform is type "duration", which provides unambiguous documentation as well as the ability for tools to do automatic validation.

That means that XML schemas, strictly speaking, are not compliant with the requirements. However, the message handling and CPA/CPP specs have already used XML schemas, so you all would be just one more not in compliance...
