Description

The idea is that instead of doing this as we currently do:

<ServiceProvider id="My DataSource" types="DataSource">
JdbcDriver org.hsqldb.jdbcDriver
JdbcUrl jdbc:hsqldb:file:data/hsqldb/hsqldb
UserName sa
Password
JtaManaged true
</ServiceProvider>

<ServiceProvider id="My Unmanaged DataSource" types="DataSource">
JdbcDriver org.hsqldb.jdbcDriver
JdbcUrl jdbc:hsqldb:file:data/hsqldb/hsqldb
UserName sa
Password
JtaManaged false
</ServiceProvider>

You can inherit from another <ServiceProvider> element and update the defaults

<ServiceProvider id="My DataSource" types="DataSource">
JdbcDriver org.hsqldb.jdbcDriver
JdbcUrl jdbc:hsqldb:file:data/hsqldb/hsqldb
UserName sa
Password
JtaManaged true
</ServiceProvider>

<ServiceProvider id="My Unmanaged DataSource" parent="My DataSource">
JtaManaged false
</ServiceProvider>
