You don't need to add an explicit namespace declaration. Instead just add

Attribute a = new Attribute("xsi:schemaLocation", 
"http://www.w3.org/20001/schema-instance";, "foo/bar");

Every element you create in a namespace shoudl be given its namespace in 
Java. e,g,

Element foo = new Element("foo", 
"http://www.oenorm.at/schema/A2063/2009-01-15";);

XOM will figure out where to put the namespace delclarations. You only 
need to call addNamespaceDeclaration if you have namespaces in attribute 
values that do not appear in element content in the same scope, or if 
you want to move a namespace declaration higher in the hierarchy 
(usually to the root element) than it would naturally appear.
