  17. From the January draft standard:
  18.  
  19. 1 A template can be referred to by a template-id:
  20.           template-id:
  21.                   template-name < template-argument-list >
  22.           template-name:
  23.                   identifier
  24.           template-argument-list:
  25.                   template-argument
  26.                   template-argument-list , template-argument
  27.           template-argument:
  28.                   assignment-expression
  29.                   type-id
  30.                   template-name
  31.  
  32.  
  33.  Notice the third-last line, "assignment-expression". 
  34.  
  35.  Call me dumb, but I must ask what does this mean? What does the 
  36. expression specify, a type or a value? Will an assignment be made at run 
  37. time?
  38.  
  39.  Can you give me any examples of templates specialised with an 
  40. assignment-expression?
  41.  
  42.  
  43.                          Thankyou.
  44.
