Let me try again. Suppose we have:

	<li><a href="#l1>src one</a>
	<li><a href="#l2>dest two</a>
	<li><a href="#l3>dest three</a>

	<li><a name="l1">dest one: legal and works</a>
	<li><a name="l2">dest two: illegal, but works
	<li><a name="l3"></a>dest three: legal, but doesnt work

You will find:

link	works with Mosaic	parses by current DTD
2	YES			NO
3	NO			YES

I see no reason why link #3 shouldn't work. That it does not, I consider
a bug in Mosiac.

I also see no technical reason why link #2 shouldn't parse. But
it currently doesn't, and the sentiment is that it shouldn't,
on the grounds that allowing folks to omit </A> is confusing.
