RE: Sweet nostalgia
Pretty much the case. XML is syntax. An XML parser is expected to find syntax errors and As Much Structure As You Provide In A DTD/Schema. Everything interesting past the syntax parse is in the application language. XML Doesn't Care. An application can structure down to individual characters if it cares enough but if one cares that much, XML is likely not the best syntax to use anyway. There may be some undefined boundary but it would likely not be discovered by the structure but entropic measures of the system itself. And that might be the best response for the XML Core WG to make to Berners-Lee's request: XML is not the right place to solve the particular problem of having a transmission format that is invariant to transformation into and out of alternative formats. It is interesting to note that after the CAD WG of the Web3DC debated the merits of a standard for CAD on the Web, they talked in terms of a JPEG for CAD, not a markup language. len From: Hunsberger, Peter [mailto:Peter.Hunsberger@s...] Hmm, I don't think I buy this argument. This gets a back to Len's question about "noise" and my response about error correction. While it is true that XML carries with it some extra information that makes it somewhat more robust in the face of corruption it isn't true that this extra information allows you to understand what the errors where. (Nor is it true that all binary formats are useless in when a byte is "blown", many of them carry enough information that errors are recoverable.) The fact is, the extra information in XML isn't of a form that allows you to do robust error recovery. It might allow you to decide that you understand some portion of the document, but if a document is corrupt do you really want to assume that a missing end tag is the only problem and that the real problem isn't that an entire paragraph including the missing end tag got deleted?
