Re: XPath and a continuous, uniform information space

Intriguing, Uche! You write:

"My own idea is to expand beyond that to support callback-type processing within the XML parse phase, triggered according to node patterns, which could support actions such as retrieving resources from the Web to produce additional or modified nodes.  I prefer that separation, and I can also imagine other uses for such a system, including additional and more efficient schema and transform mechanisms."

So you speak of "node patterns", "processing" and "actions". Do you think of associating nodes with something dynamical, something reminding of functions - the definition of a processing, to be triggered by the XML parser coming along?

And I wonder if such associations could be regarded as resources themselves (or part of the resources), so that the result would resemble an object in the OO sense - data plus behaviour. Or perhaps I misunderstood? ...
