Thanks for the two links, > See http://www.w3.org/TR/2003/WD-DOM-Level-3-Val-20030205/validation.html > and http://xml.apache.org/xerces2-j/faq-dom.html#faq-7
but the contents of the first one seems to be not implemented in current xerces version. There is no package org.w3c.dom.validation. For the second one: I think it is a little bit too much, to revalidate the complede document if only a single attribute of an element has changed. Is there no easier way?
