Re: Partial Validation by DTD


> A bonus question is: How is the same objective obtained using XML Schema?

I was always one for skipping the main assignment and doing the *more fun*
extra credit.  In XML Schema you would use the "any" element [1].  By
setting the namespace attribute you can control what types of elements are
contained within your "any" section.  Possible choices are

##local (declared in this namespace)
##other (declared outside of this namespace)
or you can specify a namespace of allowed elements.

Good Luck,
