<!ENTITY % pattern "(root | (target-element | element | any)*>
<!ELEMENT rule (%pattern;, %action;)>
Is the asterisk in the entity correct? What this means is that I can say that
the ancestor of the target element has specific siblings:
<element type="foo"/>
<element type="bar">
<target-element type="foobar"/>
</element>
Section 3.2.1 discusses this possibility for the descendants of a target element
("Multiple element elements can be placed *inside* a target-element element.")
but not for its ancestors.
