Not quite -- if you want between 0 and 3 <node>s, you need to say it
somewhat differently, to avoid non-determinism:
<!ELEMENT node (node,(node,node?)?)?>
To add attributes, just do
<!ATTLIST node attr1 CDATA #IMPLIED
attr2 . . .>
Please note in future that this list is for W3C XML Schema discussion.
