-An \type {attribute_list} item is used as a head pointer for a list of attribute
-items. It has only one user|-|visible field:
+An \type {attribute} comes in two variants, indicated by subtype. Because attributes
+are stored in a sorted linked list, and because they are shared, the first node is a
+list reference node and the following ones are value nodes. So, most attribute nodes
+are value nodes. These are forward linked lists. The reference node has fields:

-A normal node's attribute field will point to an item of type \nod

-defined \quote {attribute} item, whose \type {next} will point to the second
-\quote {attribute} item, etc.

-As mentioned it's better to use the official helpers rather than edit these
-fields directly. For instance the \type {prev} field is used for other purposes
-and there is no double linked list.
+Because there are assumptions to how these list are build you should rely on the
+helpers, also because details might change.
