For now, you could cast the ExpressionContext to an
XPathContext.XPathExpressionContext and use the getDTMManager() method,
like this:
public MyExtFunction(ExpressionContext xctxt, ...) {
...
DTMManager manager = ((XPathContext.XPathExpressionContext)
xctxt).getDTMManager();
...
}
I'm not sure if we should add this method to ExpressionContext since
someday it might not be available for all expression contexts, maybe.
Of course, in that case, we could always return null.
Scott, what do you think? I'm in ExpressionContext anyway with the
getVariable(..) support.
