The DTD can't express details like "hreflang= should be
only used if href= is present", or "at least one of href=
or id= is required", or "if name= is used its value must
match the value of id=".

The validator uses the DTD, and the DTD doesn't specify
these details. Something like <a hreflang="en">oops</a>
is probably valid w.r.t. the DTD. And if that's the case
<a name="foo">bar</a> is also valid.
Just for fun I've just tested it, the validator accepts
this as valid. Even for XHTML 1.0 strict. Of course it
won't work for XHTML 1.1 => there is no attribute "name",
but the weird <a hreflang="en">oops</a> is still valid.
Bye, Frank
