Re: TOUGH ONE: All Grandmasters - how- iteratable key-

Sanwal,

The lack of progress with constructive replies to your problem must be
indicative of something -- you have failed (until now) to give a simple and
precise formulation of your problem.

I hate to put significant effort in guessing -- whoever needs help must do
their side of the job and provide a complete (smallest posible) example with
the complete source.xml, the complete desired result, the complete
definition of the required properties of the transformation.

Reading your message it *seems* to me that everything you're speaking about
is possible, however the only prove (and not just general chatter) would be
when a complete example is given and solved.

If you are unable to provide a compact example this means that probably you
have some problems in understanding your problem -- in this case it is not
meaningful for anybody to try to help, as we are not sure what you're
speaking about.

Therefore, the next big step in solving the problem will be to define it.
