Note that it is a quote from the Architecture of the World Wide Web Recommendation. Maybe it should be reconsidered if that Recommendation is ever republished, and perhaps we should not have included it without qualification in the note sent earlier today.

However, the call for benchmarks seems reasonable to me, as does the advice that such benchmarks should involve the "best shot" for the text case. One thing that is unclear to me, however -- does this "best shot" include the use of MTOM and XOP for binary attachments? If so, the distinction between text and binary becomes a little unclear to me. I must admit that as far as the usage case I personally submitted to the XBC it seems to me that MTOM could probably be made to "do the job", although a true binary standard would do it more neatly and flexibly. My understanding, however, is that there are other usage cases for which MTOM won't really work, but it seems to me that documenting this very clearly would be a good idea. On a truly trivial note, do you think you could adjust your email client so the line wraps work in my email client (Outlook)? Your paragraphs each display for me as one very long line. -----Original Message----- From: public-xml-binary-request@w3.org [mailto:public-xml-binary-request@w3.org] On Behalf Of Rice, Ed (HP.com) Sent: Tuesday, May 24, 2005 12:26 PM To: www-tag@w3.org; public-xml-binary@w3.org Subject: TAG opinion on XML Binary Format TAG opinion on XML Binary Format The TAG has reviewed in detail the documents [1,2,3,4] prepared by the XBC workgroup [5]. While we very much appreciate the significant progress that these notes represent, the TAG believes that more detailed analysis is needed before a W3C Binary XML Recommendation is sufficiently justified. We are taking no position at this time as to whether Binary XML will prove to be warranted, as there seem to be good arguments on both sides of that question. Rather, we are suggesting that further careful analysis is needed before the W3C commits to a direction. The TAG believes there are disadvantages as well as potential advantages that will result from even a well crafted Binary XML Recommendation. The advantages are clear: a successful binary format is likely to provide speed gains or size reductions, at least for certain use cases. The drawbacks are likely to include reduced interoperability with XML 1.0 and XML 1.1 software, and an inability to leverage the benefits of text-based formats. These are important concerns. Quoting from the Web Architecture document[6]: "The trade-offs between binary and textual data formats are complex and application- dependent. Binary formats can be substantially more compact, particularly for complex pointer-rich data structures. Also, they can be consumed more rapidly by agents in those cases where they can be loaded into memory and used with little or no conversion. Note, however, that such cases are relatively uncommon as such direct use may open the door to security issues that can only practically be addressed by examining every aspect of the data structure in detail.
