Is there any way to 'park' values for later use

[Jim Talbut]

Hi,

I want to provide a single web service that makes calls to two separate 
web services.
The arguments for the two services are different and some of them are 
independent, so the service I offer will have a combined argument list, 
and I need to do a couple of transformations to generate the arguments 
for the called services.

What I can't see is how I can store arguments for the second service 
that are not required for the first service so that I can access them 
again in the transformation for the second service.
I could do this quite easily with a couple of custom processors, just 
adding the initial data to the exchange, but I'd like to know whether 
there is any way to do it without custom processors.

Thanks

Jim
