According to the HTML 2.0 DTD, the second item is legal, but the DTD is
setup that the second item will could become illegal in future
versions. I believe it is currently set up to be more backward
compatible than enforcing the newer style.

My minor grievance about the possible future usability of the anchor
element is that STRONG and EM elements will not be allowed in an
anchor. For example:

<H2><A NAME="foo">The <CODE>FOO</CODE> command</A></H2>

seems fine for me on a stylistic point of view, but will be illegal.
The future content model of the anchor is supposed to be the

(#PCDATA | IMG | BR)+ -(A)

I figure if you are going to allow #PCDATA as part of the content
of an anchor, then the character based style elements should also
be allowed.
