Break your XSL into multiple templates

It's good practice to use many templates rather then one with "hidden" elements.

BasePeriod:

    
        
            
        
        
            
        
        
            Periods
            

                
                

                    

                        
 Start Date 
                        
 End Date 
                        
 Sub Periods 
                        
 Type 
                    
                    
            
        
    

    

Period:

    
        
            
        
        
            
        
        
            Sub Periods 
            

                
                

                    

                        
 Start Date 
                        
 End Date 
                    
                    
            
        
        
            
        
    

subperiod:

expandIt:

---

As you see I changed:

to:

(same for per_expand). Result (using Opera):

Next (clicking Periods link):

Next (clicking sub periods):

It seems to be ok, expanding and collapsing work as expected.
