No, the only method for turning on schema validation with JAXP 1.2 is to use the "http://java.sun.com/xml/jaxp/properties/schemaLanguage"; property. When you set the schemaLanguage property, JAXP 1.2 parsers must validate against the given schema language only. You either get schema validation if the property is set or DTD validation if it is not set, but you cannot get both. DOM Level 3 supports something similar [1] to the dynamic validation feature but this is only available in JAXP 1.3 parsers. > Thanks, > Dies > > Michael Glavassevich wrote: > > Hello Dies, > > > > When you set the schemaLanguage property to > > http://www.w3.org/2001/XMLSchema only schema validation is performed.
