It is. ("empty" in the sense you meant, not in the SGML sense.)

Depends on what you mean by "fail". I haven't seen it crash.

 |3.  Is <a name="something"> alone legal, i.e. without the </a> ?

No, it's not.

That's why hyperlink targets have been changed in HTML 3.0. The <A>
tag is now used solely as a hyperlink source, while almost any other
element can function as target. For example: <a
href="#something">... </a> can link to <em id="something">... </em>
but also to <dl id="something">... </dl>.
