This is actually more a question of dynamic programming in XSL.
If you can't remember the function it is:

F0 = 0
F1 = 1
f(n)=f(n-1)+f(n-2) for n>=2

is it possible to make a template that calculates this in linear time (I
know it can be done in O(lg n) but linear is enogh) in xsl?
The straightforward recursive method for calculating f(n) is clearly
exponential in n.

If it is possible I would prefer an example using memoization because I need
it to a similar problem I have.
