Hi Marijan,

It's not possible, I believe.

Hi Mario,

If you are using the Sedna XQJ API, when executing XQuery expressions
you can add default namespaces to the static context of all queries,
for instance:

==============

XQConnection conn = MySednaXQDataSource.getConnection();

XQStaticContext context = conn.getStaticContext();

context.declareNamespace("p1", "http://www.example.com/ns/1");
context.declareNamespace("p2", "http://www.example.com/ns/2");
context.declareNamespace("p3", "http://www.example.com/ns/3");

conn.setStaticContext(context);

XQPreparedExpression xqpe = conn.prepareExpression(
  "<p1:doc> <p2:child1 /> <p3:child2 /> </p1:doc>"
);


XQResultSequence rs = xqpe.executeQuery();

// proces results of result sequence ...

==============

Because you set the connection's static context, you can continue to
execute further queries where each query already has the namespaces
declared.

If you wish the namespaces declarations to only affect a given XQuery
expression, but not subsequent calls, then you can use the following
two methods, passing the XQStaticContext properties in as required:

XQConnection.prepareExpression(..., XQStaticContext properties)
XQConnection.createExpression(XQStaticContext properties)

Hope this helps.

Regards,

Charles

Thanks Charles and Ivan for your responses.

It's too bad there is no include mechanism right now but maybe in the 
future.
