Xml Serialization: how to control field/data format?

[RC]

Hi!

I'd like to control how an int field is serialized/deserialized.
Specifically, I'd like to the value to be BINARY in the XML (since it
makes sense in the context of my program), e.g something like this:

....
<record>
<intField>00101101</intField>
</record>
....

What's the correct way to control the field's format? Is there a way
to do this using some Attribute? Or should I wrap the int field in a
class and implement my own serialization/deserialization methods?

I assume this is a common serialization problem, e.g. people probably
want to format fields, like DateTime, all the time..

Any pointers in the right direction would be greatly appreciated!
