> If an exception is thrown during org.apache.fop.fo.FOTreeBuilder.MainFOHandler.endElement(String, String, String), then the line "currentFObj = currentFObj.getParent();" does not get executed. If the SAX event source decides to store the exception and continue, then subsequent endElement calls can generate SAXExceptions of the form:
> Caused by: org.xml.sax.SAXException: Mismatch: page-sequence (http://www.w3.org/1999/XSL/Format) vs. root (http://www.w3.org/1999/XSL/Format)
> 	at org.apache.fop.fo.FOTreeBuilder$MainFOHandler.endElement(FOTreeBuilder.java:338)
> 	at org.apache.fop.fo.FOTreeBuilder.endElement(FOTreeBuilder.java:181)
> 	...
> Some implementations of javax.xml.transform.Transformer that we have used will attempt to perform further endElement calls in this way and the SAXException can hide the original Throwable, making diagnosis of problems difficult.
