To me the arrogance arises from standardizing such things to the maximum 
extent possible.  Taking a use case which seems plainly marginal and gluing 
it into a specification which affects a large number of people who don't 
actually need it imposes costs that the arrogant prefer to ignore.

The more _my_ infrastructure can do, the better.  The less _your_ 
infrastructure imposes on me, the better.  Finding a balance between those 
has always been a better idea than building the largest possible contraption.

Because the tool can operate in _your_ environment without inflicting side 
effects across the landscape.

Sure, it's useful.  Does it belong in a schema describing markup?  No, I 
don't think so.  I don't think it adds any more value than the current 
calendar disaster the WXS datatypes have already created with 
gHorribleKludge.  Calendaring is a tough set of problems.  I don't think 
maxOccurs and minOccurs in WXS does much to solve them.

It's hubris to say that "because I want this goddamn feature, you're all 
going to have it too."  Finding the right balance of features keeps us off 
each other's property while still letting us talk across the fences.  Not 
that WXS is anywhere near balanced, of course.
