RE: Nested Documents (was: XML 2.0)
Perhaps it is bizarre. This note here is all redundant information (to some extent) but I couldn't tell whether your comment it out of disagreement or out of frustration that it seems that a step backward is being taken. If it's the latter, then skip this message. However, I don't think I've heard a good solution on how to ensure that you have everything. Yes, it's a good idea to want the network to ensure delivery of everything but I don't think XML is tied to protocols that guarantee delivery. By allowing multiple root elements, either the network needs to guarantee delivery or the something in the content needs to indicate either the number of root elements (an extension of the prolog as already suggested by someone) or by indicating the end of the stream. If XML 2.0 (or whatever version) supports multiple roots, it seems that it should also support a mechanism to indicate this. The logfile use case is a great one. But I would be pretty upset if a hospital record got dropped. Or in the environment I work in, it would not be a good thing if I couldn't guarantee that a caselaw document didn't get dropped. I don't know the actual likelihood that the network would fail right in between two root elements but it's a situation that should be considered...shouldn't it?

I thought the days when you put "****" at the end of a data file because you couldn't rely on the I/O system reporting that you'd hit the end of your reel of paper tape were gone about 40 years ago.
