Thread safety of Saxon 9 Compiled Transform

Using Saxon 9 HE, it takes a few seconds to compile style sheet (in .Net).

Can any one verify that compiled transform is thread safe. i.e. If i compile style sheet and hold onto the instance to invoke in future. Will invoking this compiled Transform instance simultaneously from multiple thread cause any issue?

XsltTransformer transformer = proc.NewXsltCompiler().Compile(new Uri("file:///" + styleSheet)).Load();

//Store transformer instance as class variable and reuse it to eliminate compilation time

See the documentation on saxonica.com, you only need to compile once XsltExecutable ex = proc.NewXsltCompiler().Compile(new Uri("file:///" + styleSheet)); and can then use the XsltExecutable in several threads: "An XsltExecutable is immutable, and therefore thread-safe.".

About XsltTransformer, it says "An XsltTransformer should not be used concurrently in multiple threads. It is safe, however, to reuse the object within a single thread to run the same stylesheet several times.".
