	Perhaps I haven't grapsed what is the problem with <A>.
People with clients which did not implement SPOT are tempted to use:

	<A NAME="target></A>Blah blah ...

for what:

	<SPOT ID="target">Blah blah ...
	
does.  Using:

	<A NAME="target">Blah</A> blah ...

avoids the problem of an empty anchor, but including some arbitrary,
small portion of the text as content is not logically what's intended.
Also, it achieves the desired result only for clients which have stopped
highlighting anchor content if the anchor tag lacks an HREF attribute.
In those cases, forgetting to include an end tag for the anchor has
no visible consequences (the client doesn't highlight, or otherwise
indicate a link, for a large portion or everything which follows the
HREF-less NAMEd anchor start tag).  So naive users of such clients
draw the incorrect inference that an end tag is not required for
NAMEed anchors without an HREF.  That's not a bug in the clients which
needs to be corrected, but is a predictable consequece of the clients
not supporting markup which is explicitly designed for what is intended.

	Along the same lines, for your initial example, with the HTML 3.0
DTD a valid way to do it is:

	<H1 ID="target">Blah blah ...</H1>
	
	What are the current status and future prospects for ID attributes?
