DOM L2 does neither support directly nor interface with any query-like
language such as XPath. It is to me ok but there is one piece of information
which is not accessible through DOM L2, which makes it rather difficult to
implement XPath atop. Those are IDs. In other words, it is not possible to
make XPath implementation independent of XML parsers supporting DOM L2 since
the use of back-door APIs are inevitable to retrieve ID-related information.
