Okay, but if you normalize them, the input would need to look like this:

<a name="foo"/>
<a name="bar" depends-on="foo"/>
<a name="baz" depends-on="foo"/>
<a name="jaz" depends-on="foo"/>
<a name="jaz" depends-on="bar"/>
<a name="spaz"/>
<a name="maz" depends-on="spaz"/>
<a name="maz" depends-on="bar"/>

I don't think your code would work for this form. This is where I ran
into the roadblock. How do you print out jaz only once even though it
occurs as a dependent of both "foo" and "bar"? Maybe I can do something
with preceding::. I'll pursue that route.
