You haven't said *how* you are running Saxon. 

When you call the document() function Saxon will create (or reuse) an XML
parser. The XML parser will attempt to locate the DTD using its
EntityResolver. You need to make sure that the XML parser is preconfigured
to use an EntityResolver that searches the catalog. The usual way to do that
is to use the -x option on the command line.
