I'm not aware of one, no. JIRA to fix that is [1].

The <datasource><module> element is confusing, as it's oddly named for 
the way it's used in the AS.[2]

The value should be

driver-fqcn#<driver-major-version.driver-minor-version

where driver-fqcn is the name of the class that implements driver.

There are two ways to make the driver available.

Simpler is by deploying the driver jar (same as you'd deploy a war, etc).

More complex is by creating a module for it in the modules/ dir; e.g. 
$JBOSS_HOME/modules/com/h2database/h2 and then adding a child element 
under <subsystem xmlns="urn:jboss:domain:datasources:1.0"><drivers>. A 
jar in the module needs to include a META-INF/services/java.sql.Driver 
file whose contents are the FQCN of the java.sql.Driver implementation. 
(The AS loads the driver from the module using java.util.ServiceLoader).

Don't know if [3] will help.
