Question: constraint terminology

Question: Could somebody explain the following terms:

- Global constraints
(the FAQ says: "constraints with maximum arity", does that mean that if
the problem contains N variables only N-ary constraints are considered
global?)

- Specific and structural constraints 
(in: CHIC lessons on CLP methodology, ECRC-report)
A lot of applications (I think) contain both a set of reasonably stable
(permament) constraints as well as constraints that change from problem
to problem instance, is that what is ment here?

Also I would appriciate pointers to papers that explicitly deal with
problem solving systems for a combination of continuous and symbolic
constraints.

Thanks in advance, 

Peter Schotman
