Re: [xml-dev] Is it valid in XSD to have choice where all particles are optional

XSD is probably the most difficult spec I have read since Algol 68. The 
difference is that the more you read the Algol 68 spec, the more it 
makes sense; whereas the more you read the XSD spec, the more holes you 
find.

The wonder is that despite all its faults, a large number of people are 
getting a large amount of value from it.
