Are the XSLTProcessor and StylesheetRoot (compiled stylesheet) objects thread-safe?
The XSLTProcessor stores running state information, so it is not thread-safe. If you want to use the XSLTProcessor to perform multiple transformations, create a new instance for each transformations or synchronize. If you want to perform multiple serial transformations with a single XSLTProcessor object, call the XSLTProcessor reset() method between each transformation. StylesheetRoot objects, on the other hand, are thread-safe. A single StylesheetRoot object may be called concurrently from multiple threads. For more information, see the next question.
