Issue a trace message, which is sent to the trace file.

The output goes to the configured trace file. If traceoptions is enabled, but no trace file is explicitly configured, the output goes to the default trace file for that script type.

The prefix associated with the namespace URI should be defined in the prefix-to-namespace mapping in the style sheet.
