Sure...but I was only discussing this for illustrative purposes, showing how the real-world task of defining HTML is in between the two ends of a spectrum. > Those familiar with TeX know that, > being a macro-based language, one can layer onto the base > constructs (the small finite set of TeX primitives) as > many elements of syntactic sugar as one wants.

I totally agree, but that simply means we need to create such mechanisms. > HTML is > handed down from on high, and we lesser mortals can take it > or leave it. I thought the same about 4 years ago, and I used to curse louder than most! But then I concluded that really I should try to get involved in the development of the language, rather than moaning. I got into a dialogue with the Working Group, and then found myself invited to be an...well, an Invited Expert. I know not everyone wants to do that, but at least my experience shows that the W3C is not the Nomenklatura. > Most of us are forced to take it, but it > leaves a sour taste in the mouth knowing how much richer > the language /could/ be if one could extend it at will > to cope with the requirements of the task at hand. That's *exactly* where I am coming from, too. I got involved because I was trying to build dynamic UIs based on RDF Schema. However...the problem is not an easy one to solve, since how can you add stuff to your language that my processor can understand? We need to agree on an extension language. > I don't ignore (or even underestimate) the difficulties > that this poses, but I do so wish that this concept of > extensibility had been uppermost in mind when HTML was > first conceived. I sympathise, but that's a bit like saying we wish James Watt had thought a bit more about powered flight when he created all of his steam engines--they are different eras. In fact, we can only think today about the things we would like to do, because many years ago some clever people came up with tagged languages delivered over a network. > And yes, I know one can write a custom > DTD (I have, on more than one occasion) but without > a formal requirement that HTML renderers ("browsers") > be /required/ to honour non-standard DTDs, such an > approach can be of only very limited use. Of course. It's OK, you have defined the problem, all I am is that it's time to try and solve it, rather than wishing it had been solved many years ago.
