And it is equally mad (or maddening) to eschew XML syntax and step back five years because of some aberrant cases. Dave and Andy have a very good point to make, but the way they make it undervalues the role of grammar design in both XML and plaintext. RelaxNG XML syntax may [expletive deleted], and the compact syntax may be beautiful, but it took effort to *design* a beautiful, simple plaintext syntax. Ditto RDF/N3. Ditto YAML. A slap-dash plaintext syntax is often *worse* than a similar XML vocabulary, because the reliance on (raw) XML alleviates many common problems. Doubly so if you're expecting a format's users to grovel through a poorly design plaintext format with their own buggy parsers or regexes. > Getting back to Andy and Dave.

Dave had some positive words to say about XML usage, especially in the small or well-designed domains: Now, for some things there are standards. For example, there are some standards like RSS and RDF, which give you very simple ways of describing web page content. But a random XML file, especially machine generated XML files, can be as obscure as binary data. ... and XSLT: If you're talking about using XML in certain domains, it's fine. XSLT, for example, lets you do some really fun things with XML. The bad end of the spectrum is certainly getting worse, but that's not sufficient justification to "follow the trends", assert that it's *all* bad, or even accept bad vocabulary design. The solution here is to (1) design better vocabularies (and reject the bad ones, when possible) and (2) avoid XML where it's inappropriate. In that order. Z.
