I can't handle all them funny characters. I do use the Microsoft XML Schema preview though, because I think the principles are sound, even if the spec is continuing to evolve. In other words I think validation is an important issue. > I do agree that for the vast majority of (even embedded) apps that > the parser footprint is not an issue.

It's possible that I may be denying some inner desire to be pro-SML! But I doubt it. My point is based on an assumption that I haven't dared air in public for fear of death threats. It is simply that it won't be that long before there becomes little point in talking about XML 'as such'. For example, I have developed a layer to allow my clients to update all sorts of data on my server. The data is stored in a database, but appears to be files to them, through a WebDAV interface. For the author information stored in the database I use the XML version of vCard; for the magazine articles I use XMLNews-Story; for the subjects that link people and articles together I use Dublin Core, and to create contents pages and publication information I use RDF. When PageMaker articles are imported they get converted to XHTML before being converted to XMLNews-Story. Oh, and SOAP is used to get some other bits and bobs from another server. Now, am I using XML? Well of course I am, but I'm also using binary, electricity, RDBMS, C++, COM, blah blah blah. Sure, XML is still new enough for it to have its own mailing list - just like electricity would have done if it could have. But after a while you have to say that the 'concepts' of RDF, SOAP and WebDAV are something that is more than the fact that they use XML for their implementation. Eventually XML will be 'seen' by the equivalent of particle physicists today. The rest of us mere mortals will use their parsers, editors, class libraries, protocols, and so on. I feel that to a certain extent the point I am referring to may have already arrived on this list. The guys on the WebDAV list, for example, are not discussing whether their spec is too complicated. They're getting on trying to solve conceptual problems. And we will all benefit from it. I would have no problem, for example, seeing a discussion under the general heading of XML about how we can build tools that 'hide' the DOM from programmers. Microsoft just posted something like this up on BizTalk. I'm still in two minds as to whether I could use this approach in my code. What do others think? Or what about developing layers that pull XML in and out of databases without other programmers needing to worry about what's underneath? Anyway, I do think we should aim up not down; rather than trying to throw away stuff which is of fundamental significance, let's develop things that make those important techniques easier to take advantage of.
