I we removed the "if it has any resources that require releasing."
I'd be with you.

I'd prefer all components to have one way of releasing them,
so you didn't have to check for specific implementation details
(requires release), but could just treat all components the same.
That is,
A component interface must define a method with the following
signature:
public void release();
or a component's manager (if it exists) must define a method
with the following signature:
public void release( Object );
Period.
Much easier to code for. I'm also fine with the release() method
being called close() in some components and endDocument() in some.
Just that there is one.
