How to configure multiple datasources with the single security policy in wildfly - wildfly

Question

I have setup successfully two data sources using different encrypted password policies as follows:
Security policy 1
<security-domain name="policy1" cache-type="default">
<authentication>
<login-module code="org.picketbox.datasource.security.SecureIdentityLoginModule" flag="required">
<module-option name="username" value="user1"/>
<module-option name="password" value="-16de44"/>
<module-option name="managedConnectionFactoryName" value="jboss.jca:service=LocalTxCM,name=DATASOURCE_1"/>
</login-module>
</authentication>
</security-domain>
Security policy 2
<security-domain name="policy1" cache-type="default">
<authentication>
<login-module code="org.picketbox.datasource.security.SecureIdentityLoginModule" flag="required">
<module-option name="username" value="user2"/>
<module-option name="password" value="-16de44"/>
<module-option name="managedConnectionFactoryName" value="jboss.jca:service=LocalTxCM,name=DATASOURCE_2"/>
</login-module>
</authentication>
</security-domain>
Datasource 1
<datasource jndi-name="java:/DATASOURCE_1" pool-name="DATASOURCE_1" enabled="true">
.
.
<security>
<security-domain>policy_1</security-domain>
</security>
</datasource>
Datasource 2
<datasource jndi-name="java:/DATASOURCE_2" pool-name="DATASOURCE_2" enabled="true">
.
.
<security>
<security-domain>policy_2</security-domain>
</security>
</datasource>
However, I would like to know if it's possible to use the same policy for both datasources? I haven't been able to find a way to include more than one pool_name in the managedConnectionFactoryName policy attribute:
<module-option name="managedConnectionFactoryName" value="jboss.jca:service=LocalTxCM,name=DATASOURCE_1 ??????, DATASOURCE_2 ?????"/>
Is the managedConnectionFactoryName attribute absolutely necessary? what could be a side effect if this attribute is not added?

Answer 1

Does this answer your question? https://access.redhat.com/solutions/304063
That means:
<module-option name="managedConnectionFactoryName">jboss.jca:name=DS1,service=LocalTxCM</module-option>
<module-option name="managedConnectionFactoryName">jboss.jca:name=DS2,service=LocalTxCM</module-option>

Answer 2

It seems that Wildfly 8.2 prefers this syntax:
<module-option name="managedConnectionFactoryName" value="jboss.jca:name=DS1,service=LocalTxCM"/>
But, It still does not seem to honor the security-domain for more that one datasource.
Does anyone know the significance of
service=LocalTxCM
in the example above? Seems like this would be different for xa-datasouces.
