Is it necessary to use XA-Datasource in Appian 7.3? We have Service Corp databas

Tim,
I am updating server from 6.6 to 7.3. My datasources are non XA-enabled so I was wondering if I need to do anything different in configuration. As per Appian relational database configuration documentaion for sql server, we need to add the following code in standalone.xml:
<subsystem xmlns="urn:jboss:domain:datasources:1.0">
<datasources>
<drivers>
<driver module="com.microsoft.sqlserver.jdbc" name="com.microsoft.sqlserver.jdbc">
<xa-datasource-class>com.microsoft.sqlserver.jdbc.SQLServerXADataSource</xa-datasource-class>
</driver>
</drivers>
</datasources>
</subsystem>

so I was wondering if the "<xa-datasource-class>com.microsoft.sqlserver.jdbc.SQLServerXADataSource</xa-datasource-class>" is needed to be changed or it can be there without any chages?
