c# - XmlDocument.Save() inserts empty square brackets in doctype declaration

Question

Everytime I call the method on

XmlDocument.Save(fooFilepath);

it inserts two square brackets at the end of the DOCTYPE tag e.g.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ARCXML SYSTEM "G:ArcIMSDTDarcxml.dtd"[]>

Does anyone know why this might happen? I obviously don't want this to happen.

Answer 1

That is a normal (and optional) part of a DOCTYPE declaration.

<!DOCTYPE rootname SYSTEM url [DTD]>

Where DTD contains any internal subset declarations to your document.
