And yes, latest xerces supports/implements this featue. Andrea Bigger wrote: Hi. In the W3C Recommendation I found following statement: << [...]. The fixed attribute is used in both attribute and element declarations to ensure that the attributes and elements are set to particular values.

I'm currently using JDOM v1.0b8 on top of Xerces-J v2.4.0 and every time I try to get a value of an unset attribute/value which should have a fixed value, I get a null reference. JDOM uses a org.apache.xerces.parsers.SAXParser, validation is enabled and feature http://apache.org.xml.features/validation/schema is true. The schema processor seams not to work properly. What could be wrong? Thanks for help/hints.
