   RE: [xml-dev] malfunctioning, evil adult as XML

[ Lists Home | Date Index | Thread Index ]

My experiences with Erik indicated that he 
doesn't suffer from his tortures; he quite 
enjoys them.  He is a very sharp fellow.

That aside, I am teasing the programmers a 
bit (I am one too) but to point out the distinction 
of XML as something the average bear can master 
versus the extremes of real programming languages 
that require mastery.  If we push too hard toward 
PLs, we break the contract with the rest of the 
user and implementor community.  We have to be 
very careful about that sort of thing.  

This is like the XML subset issue: if we create subset 
only parsers instead of insisting that the 
application language designer take on the 
responsibility of choosing which features should 
be used and documenting that carefully (the 
document approach), we can seriously break 
the contracts that XML systems be easy to 
apply, have minimal options, and flatten 
out the footprint of code types.  There 
are costs for mathematical elegance; one 
is that processes in real time, in real 
situations do not always match the fully 
factored terms of an elegant algebraic 
notation.  Life is messy.

Programmers I have met have little problems with the distinction 
1. Elements map to tables map to objects
2. Attributes map to columns map to properties. 
3. Contained elements are children records are object pointers.

Perhaps the analogy we should be using about Mr. Naggum is that of a parent
who dreamed of a child becoming a lawyer and was bitterly disappointed when
she became an architect. Logic and structure matter in both cases, but the
constructions are vastly different and used for different things. At root
logic and structure are branches of mathematics.

It was very sad reading that. What a tortured life he must lead.
