very true, if MS Office wants to define an interface for other
applications, well and good. Why should we look into the inner functioning
of MS Office?? But as Len pointed out, there needs to be standard binary
format for other cases??

Regarding PIs, however, I am still not convinced totally. If I have a
latex file and I compile it, all I can get is a dvi file. However, there
are chances of overlooked sideeffects when we have a s/w that "compiles"
an XML document..?? the s/w needs to know to handle the PI, but still...
Anyways, best, murali.
