that's interesting...  so in other words... if i pass $xml->note  to a
function, the memory of exactly 1 node is passed.

in other language... a linked list will have a member variable $next
that explicitly points to the next member...

so in PHP, it looks like a node, without having a $next... and yet it
is a linked list.

and print_r will print it as an Array type.
