Re: [xml-dev] XPath and a continuous, uniform information space

David, Chris,

little thought experiment. Starting point: the info space (= sum total of all available XML documents) is a node forest. Now the experiment: (a) imagine a single invisible "space node" (analogous to the invisible document node) to be parent of all document nodes; (b) reinterpret doc("http://foo.xml") to mean: root()/../document-node()[document-uri(.) eq 'http://foo.xml'].

In other words: regard doc("http://foo.xml") to be a notation of the two-step navigation (i) up to the space node, (ii) down into the document node of interest. So that is my answer to Chris: the value of


is the space node. End of thought experiment.

For example, what does the following mean?
In the spirit of "The Information Space" that would be "The Information Space" which is not a node().
