Default Values in Attribute Patterns

It is possible to specify a default value for an attribute which is used if the attribute is not present in the element being matched. This is illustrated in the following example:

(sxml-match '(e 3 4 5)
  [(e (@ (z (,d 1))) ,a ,b ,c) (list d a b c)])

The value 1 is used when the attribute z is absent from the element e.
