Hi Jonathan. Clearly this is the day for deja vu: http://lists.xml.org/archives/xml-dev/200108/msg00705.html The point I wanted to make last year was that the marked-up syntax is processed in order to elaborate specific semantics. A map is an infoset understanding of the territory--a tightly constrained set of chosen semantics presented as a base instance in its own right. For a great many subsequent operations that map is an entirely suitable base instance, just as an infoset is for processes designed to operate against it. Yet you understand quite clearly that for the most undeniable hard physical realities the map is not a suitable base instance because you cannot serialize or otherwise realize the physical terrain back out of it. For memories of childhood or the smell of onions the desired mimesis can, in fact, be processed from a map-like infoset base instance. That is a principal function of art. For Alpha Centauri, a black hole, or even your grandfather's axe, attempting to recreate the physical from the abstract plan quickly indicates why it was counterproductive to abstract away in the first place what appeared to be purely concrete quirks. So too, I would suggest, with marked up text. In simplest terms, abstracting away anything from the syntactic instance implies, as a first premise, some 'intended' use of the document, some 'expected' processing of it, or some other abstract view which, when carried out in infoset creation, will necessarily curtail some semantic possibilities of the base text. Those intentions and expectations form the semantics of the Infoset, though John would claim there are none such. The real question is how certain are we that what we expect will be done with a document is sufficiently comprehensive that we will ab initio curtain any other possibility by asserting that there is nothing of value to in the base syntax which is not provided for in a well designed infoset.
