I would use an external variable and a set of functions (increase, 
decrease, getValue) defined using the script element from the 
http://www.exslt.org/functions namespace.

I think when you want to increment/decrement a variable, you may be 
justified to escape to a procedural language and to increment/decrement 
a variable simply. XSLT is not designed for this task and all other ways 
are more or less workarounds, IMHO.

I see this is not a "pure XSLT" solution but I think it's appropriate 
for this non-XSLT task.
