[xml-dev] When to Validate XML Guidelines

["Magick, Brian" <Brian.Magick@COMPAQ.com>]

I am curious whether any one or their organizations have developed "When
to Validate" guidelines for their XML efforts?  For example, many in my
organization would argue to always validate (these being the data
architects!) and those who work application integration issues, where a
relational database resides at each end of the XML flow, would argue
that validation in their world is NEVER necessary.
 
In this example and in others I have heard many compelling arguments
from each side, but nothing definitive.  Any thoughts or best practices
in general regarding when to validate XML?
