Hello.  I'm migrating an application to Saxon 8.9 B.  In the application, the stylesheets won't compile.  However, when I compile them from the Saxon command line interface, they compile just fine.  They do give the warning about XSLT1.0 under a 2.0 processor, but it works. 
What can be the difference?  Are there some different default configuration values using the command line versus using the application api?  Could it be that the command line is using some other resources, e.g. xml parser, that the application isn't using?
