How do you mean "differs from API to API"? Do you mean SAX/DOM/XNI?
What I was missing for the DOM version was exactly 3 lines of code -
even less than my original estimate. Reading the SAX snippet
(http://xml.apache.org/xerces2-j/faq-xs.html#faq-6), would have one
believe that no configuration is needed, and the PSVI will be
available by default; the code is therefore quite short. But I
