Both are possible. Currently we just have one exception for both 
cases. If the exception is thrown by a constructor, it probably a 
problem is a problem in the XSL file. (It could also be a plain 
vanilla IOException, but TrAX doesn't throw those separately. We 
could always check that with getCause or getException though.)

If the problem occurs during the transform the most likely causes are 
an IOException or a malformed input document. There are also a few 
cases where a stylesheet bug is not exposed except with the right 
input document. Many of these cases are optional to report. That is, 
some engines will throw an exception and others will recover. 
However, these are rare. This is much less common in practice than 
IOExceptions and malformed input documents.
