I don't have time to study your problem in detail, but looking at the summary: The real problem I think that is that the param $currentpage never gets to <bbwps:navigationMenu-pageHere/> because is inside some HTML, is this true? or the param buble down the parsed XML all the way? I think it's likely that you're falling into the trap that if you do an apply-templates with parameters, and there's no explicit template rule for one of the child elements, then the built in template rule gets invoked, which calls apply-templates on the grandchildren, but (in 1.0) without passing the parameters on to the template that matches the grandchildren. (This changes in 2.0).
