Appendix F of the ISO SGML standard compared attributes to command parameters. Yes, it's one of a number of places where XML could be made easier to implement, but also a reinder that XML (like SGML) is about modelling documents rather than defining a format convenient for any specific program to parse. It's equally inconvenient for all programs :) On the other hand, being able to say, e.g., that a namespace declaration must come earlier in a start tag than any use of that namespace (other than the element name itself which for historical reasons is always first) would for sure facilitate processing. Round-trip parsing of JSON similarly suffers from reordering of hash values. For my part I'd like to have attributes with structure, e.g. by designating an xml:attributes element as the first non-whitespace child of an element, but the result you get isn't really XML, and it quickly gets inconvenient for hand markup of documents. -- Liam Quin - XML Activity Lead, W3C, http://www.w3.org/People/Quin/ Pictures from old books: http://fromoldbooks.org/ Ankh: irc.sorcery.net irc.gnome.org freenode/#xml
