The XSL/XQuery | Start Debugger/Go command starts or continues processing the XSLT/XQuery document till the end. If breakpoints have been set, then processing will pause at that point. If tracepoints have been set, output for these statements will be displayed in the Trace window when the closing node of the statement with the tracepoint has been reached. If the debugger session has not been started, then this button will start the session and stop at the first node to be processed. If the session is running, then the XSLT/XQuery document will be processed to the end, or until the next breakpoint is encountered.
