Simple resource allocation problem

Greetings,

I am looking at a resource allocation problem that can be simplified as
follows:

two resources X and Y

X :: 1..5
Y :: 1..5

I want to allocate resources to 5 tasks each using one of each
resource. No doubleup. i.e you can only use the pair X1,Y1 once

Ususally you would use an alldifferent, but how to use this if multiple
resources are involved?

I know this looks very simple, but a number of people I have spoken to
have had trouble solving this elegantly.

I am currently looking at writing with Eclipse.

Thanks in advance.

Pat
