Back in the days of 2.0 serialization I could create a serialized version of an object that would result in the following example:

```
<transactionMessage messageDate="1/1/2001 11:00PM" messageId="abc123">
    <transaction property1="Value" property2="value2" />
</transactionMessage>

```

I would do this with the Serializable() attribute and then appending XmlElement attributes to my items. When I use DataContract/DataMember attributes though, I get something that looks like this:

```
<transactionMessage>
  <messageDate>1/1/2001 11:00PM</messageDate>
  <messageId>abc123</mesageId>
  <transaction>
    <property1>Value</property1>
    <property2>Valu2</property2>
  </transaction>
</transactionMessage>

```

Ordinarily I wouldn't really care about the XML being generated behind the scenes, but this system will be interfacing with multiple external clients who already talk to a different system (based on the 2.0 style of serialization) and I want to keep the structure similar but bring in the added enhancements of WCF.

How can I tell the DataMember attribute to essentially make the formatting more like the first sample with attributes instead of elements for everything?
