I'm making a real basic editor for spritefont files that will just read and write the XML representations so that it's a little easier to choose fonts and see what they look like before compiling. Everything's going smoothly, except when trying to write this line:

    <XnaContent xmlns:Graphics="Microsoft.Xna.Framework.Content.Pipeline.Graphics">

I tried using this code:
   
     writer.WriteStartElement("XnaContent");
     writer.WriteAttributeString("xmlns:Graphics", "Microsoft.Xna.Framework.Content.Pipeline.Graphics");

but I got an exception about the : in the name:

    Invalid name character in 'xmlns:Graphics'. The ':' character, hexadecimal value 0x3A, cannot be included in a name.

Any ideas how to write out that line some other way perhaps?

Here's an msdn example:

writer.WriteAttributeString("ISBN", "urn:book", "1-800-925")

Thanks. I found it:

                writer.WriteAttributeString(
                    "xmlns", "Graphics", null, "Microsoft.Xna.Framework.Content.Pipeline.Graphics");

Now I'm having trouble the the region area, specifically writing out the ampersand. It's trying to convert it from &#32; to &amp;#32; which is obviously not what I want. I thought using the @ was the way to have it not convert, but that doesn't work. What is the method for having it not automatically change that ampersand?

For anyone waiting for the solution too, I found that simply putting in the characters in place of the code works as well so I simply put a space for the first one and ~ for the second and it works just like normal.
