   Re: [xml-dev] Constrain the Number of Occurrences of Elements inyour XML

[ Lists Home | Date Index | Thread Index ]

I have to agree with Doug on this point that recursion is extremely 
important in some of the work that I do. The fact that you cannot 
specify a maximum depth may be troubling but it is still an extremely 
valuable construct.

maxOccurs=35000 has other problems that you don't list-- primarily that 
the FSM method of building out the validation trees struggles with a 
large upper bound according to most published algorithms. [1]

Additionally because of the versioning problems in XML Schema I would 
never recommend a solution that requires consistent updates to the XML 
Schema when such business logic could be expressed in versionable code.
