Can you elaborate a bit more about this? What are the problems
that you are referring to? Also, I dont understand how PI's can reduce
portability. It seems to me that PI's are intended to achieve the
opposite effect : if additional knowledge (than is visible to a basic
XML processor) is visible to an XML application specific processor,
then the PI serves as a signal to activate the application level
processor. This doesnt change any the semantics of the data w.r.t.
non-application specific data.
Thanks,
Kenneth
