schema constraints

["Sara Liu" <sara_liu@enfotech.com>]

HI,

 

I am a newbie in XML, please bear me with such a basic question.

 

I know, in XML schema, we can add some constraints to the elements, such as length, pattern, etc. and also, I know that XSLT and schematron can also add additional constraints to the schema. Can anybody tell me what’s the pros/cons for each approach?

 

Any help is greatly appreciated!

 

Thanks in advance!
