It is new as of 1.5.0, so expect it to change. The DOM implementation
had serious efficiency problems, IDOM is meant to replace it as soon
as it becomes stable. There are still some outstanding bugs against IDOM.

The ErrorHandler interface was introduced by SAX (I believe). Xerces
DOM and IDOM also allow you to register an ErrorHandler. During parse
it will catch any parse exceptions (not IDOM_DOMExceptions or
XMLExceptions which occurr outside the parsing itself).

There's a lot on the WWW site:
http://xml.apache.org/xerces-c/
However, there isn't much in the way of material for people not
familiar with DOM. To understand that you're going to have to find a
DOM tutorial on the WWW, or purchase a book.
