I am having trouble understanding two things in this entire discussion:
1) Why do people object so vociferously to the PSVI (other than the lack
of a catchy name and the fact that it came from an unpopular spec)?
2) How do PSVI proponents intend to use the PSVI?
As far as I can tell, the PSVI contains three groups of information:
1) Additional data values (defaults). Since this already exists with
DTDs, it seems any controversy here should have existed before the PSVI
came to being.
2) Type information. My guess is that this is where the greatest
controversy / utility is. On the utility side, it means you can do
type-aware programming. On the controversy side, it means you can do
type-aware programming :)
3) Validation information. Other than wasting space, my guess is that
virtually everybody will ignore this. It seems that the only people who
would be interested are a very small group of applications such as
validators and editors who want to tell the user where their document is
Am I missing anything else here?
