 My experiences as PM for XML Schema technologies at MSFT suggest that RELAX NG doesn't really solve the problem most developers have with XSD. Many of them use XSD as a datatyping language [at least most developers on Microsoft platforms did] in which case RELAX NG is actually worse than XSD for them since it is more expressive than XSD when in truth they need something less so. See http://whidbey.msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_fxgenref/html/07ff107a-2a2e-4bf4-819f-6a591ee54479.asp for an example of one of the reasons I doubt you'll see RELAX overtaking XSD in developer toolkits anytime soon. Another problem is that lots of vertical and niche industry standard schemas have chosen XSD as the language of choice given that it is the W3C's offering in this space. Finally, although RELAX NG is a better validation language than XSD the truth is lots of XML applications don't need or use validation. For example, I'm unaware of any XML Web Services stack that actually does schema validation on sending or receiving messages. -- PITHY WORDS OF WISDOM The only person who gets all his work done by Friday is Robinson Crusoe. ________________________________ From: Bill de hÓra [mailto:bill.dehora@p...] Sent: Sat 1/8/2005 6:05 PM To: XML Developers List Subject: Re: So, what's new in the world of RELAX NG?

What I see are people using rng as the canonical schema format and exporting it to xsd for tool usage. In other words xsd is an implementation detail; people are thinking in rng. In terms of optics, rng seems to be a victim of its own success. It doesn't conserve complexity and doesn't require much by the way of tools. Vendors are not motivated to build tools for rng. End users and developers who have come to expect to do integration work through tools don't use rng as a result of there not being tools. cheers Bill ----------------------------------------------------------------- The xml-dev list is sponsored by XML.org <http://www.xml.org>, an initiative of OASIS <http://www.oasis-open.org> The list archives are at http://lists.xml.org/archives/xml-dev/ To subscribe or unsubscribe from this list use the subscription manager: <http://www.oasis-open.org/mlmanage/index.php>
