Oups - you're right - it disappeared after we changed the list of children
into a hash table and introduced the Link object. The hash table was
required as linked lists get really slow when you have many children. This
of course doesn't solve your problem of getting the list of children.
The HTAnchor_soures() is easy to put back (or move from 4.0) but the list
of children must now be traversed internally in the anchor object and then
the caller must pass in a state variable so that we don't need to keep
state internally in the anchor (which would then be global).
