Resolving entities with crimson/SAX

Question

Hello,
I am using the crimson parser and SAX to read XML files. In the following DTD I use two entities. The second one (<!ENTITY part "downtown" >) is automatically resolved. However, the first one (<!ENTITY net SYSTEM "entity.txt" NDATA txt>) is not. I would expect a statement like: "start element: Billy Here speaks entity.txt".
Why is the data from entity.txt not included into the XML file? Is NDATA the reason ("non XML Data"). How can I include it?
DTD:
<!ENTITY net SYSTEM "entity.txt" NDATA txt>
<!NOTATION txt SYSTEM "text/plain">
<!ENTITY part "downtown" >
<!ELEMENT Customer (Adress)*>
<!ATTLIST Customer number ENTITY #REQUIRED>
<!ELEMENT Adresse (Title?,Name)>
<!ELEMENT Title (#PCDATA)>
<!ELEMENT Name (#PCDATA)>
XML:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE Kunde SYSTEM "file:///C:/Programs/Eclipse/eclipse/workspace/Saxxer/Customer.dtd">
<Customer number="net">
<Adress>
<Name>Billy &part;</Name>
</Adresse>
</Kunde>
entity.txt
Here speaks entity.txt

One more question: althouth I use the ISO-8859-1 encoding in the header of the XML file I get the warning: declared coding "ISO-8859-1" does not comply with the actual used coding "Cp1252"
Why is that?
