Driver or datasource

Hello there! I always thought that when configuring a datasource, for the driver, I should only use some driver, let me put this way :

<data-source
class="com.evermind.sql.DriverManagerDataSource"
name="myDS"
location="jdbc/myDS"
xa-location="jdbc/xa/myXADS"
ejb-location="jdbc/myDS"
connection-driver="oracle.jdbc.Driver"
username="x"
password="x"
url="jdbcracle:thin:@x:1521:x"
inactivity-timeout="1200000"
max-connections="20"
/>

Well, but I've been asked about replacing the connection-driver from oracle.jdbc.driver to oracle.jdbc.pool.OracleDataSource
and it keeps working. I just wonder how, if they are completly different classes, that have no common ancestors?

Best Regards
