1052  * simple_prop_val and complex_prop_val fill in a list structure and
1053  * insert it into the linked list which is built up.  And because
1054  * complex properties can have multiple name=value pairs, we keep
1055  * track of them in another linked list.
1056  *
1057  * The complex and list structures for the linked lists are allocated
1058  * below, and freed by recursive functions which are ultimately called
1059  * by free_cmd(), which is called from the top-most "commands" part of
1060  * the grammar.
1061  *
1062  * NOTE: simple_prop_val and complex_piece need reduction rules for
1063  * property_name and resource_type so that the parser will accept property names
1064  * and resource type names as property values.
