I agree that a web publication needs an entrypoint and needs to have all parts of the publication be reachable via internal navigation, but a linear ordering of the content seems to be only one way to achieve that. If you want to print the whole thing, you're going to have to find a way to linearize it, but it seems to me that the claim that ordering is a defining characteristic of a web publication is a tad too strong, even though it is not completely baseless.

That does not preclude (a) that a number of alternate ordering would be defined and (b) that does not mean that _all_ resources _must_ be part of that default order. It is perfectly conceivable that (to use your example below) the 'unordered.html' file is either part of an alternate order, or it is only reached via a link from a different file.

Then we are in agreement over how things should be. However, the way it is phrased and the place where it is phrased (the introduction) seems to imply that it is a defining characteristic of a publication that it be a ordered set of resources. If a publication can be composed of many unordered resources with a single one being in the default order (which you say is fine and I agree), then being ordered is not a defining feature of publications, and that sentence should probably be reworded a bit.
