But that is PHP’s implementation.  DOMXPath resembles, but does not conform 
to, DOM3 XPath.

And both of which are *optional*.  PHP implements none of them, but it 
supports alternative ways.

Your logic is flawed.  For example, the W3C DOM implementation in browsers 
does not always have such a way.

Non sequitur.
