WildFly Standalone config files difference

[cweiler]

What is the effective difference between standalone.xml and standalone-full.xml.

Find this topic in the docs:

https://docs.wildfly.org/17/Getting_Started_Guide.html#wildfly-10-configurations

It says:

standalone.xml (default)

Java Enterprise Edition 8 web profile certified configuration with the required technologies plus those noted in the table above.

standalone-full.xml

Java Enterprise Edition 8 full profile certified configuration including all the required EE 8 technologies

But this do not clarify it for me. The "table above" has a lot of checks and annotations like: 

JSR-352: Batch Applications for the Java Platform 1.0	X	—
JSR-345: Enterprise JavaBeans 3.2	XCMP 2.0Optional	X(Lite)

Then I made a diff and got this additional configs on standalone-full.xml:

<extensions>
   <extension module="org.jboss.as.jsr77"/>
   <extension module="org.wildfly.extension.messaging-activemq"/>
   <extension module="org.wildfly.iiop-openjdk"/>
</extensions>
<subsystem xmlns="urn:jboss:domain:ejb3:5.0">
   <mdb>
      <resource-adapter-ref resource-adapter-name="${ejb.resource-adapter-name:activemq-ra.rar}"/>
      <bean-instance-pool-ref pool-name="mdb-strict-max-pool"/>
   </mdb>
   <iiop enable-by-default="false" use-qualified-name="false"/>
</subsystem>
<subsystem xmlns="urn:jboss:domain:iiop-openjdk:2.1">
   <orb socket-binding="iiop"/>
   <initializers security="identity" transactions="spec"/>
   <security server-requires-ssl="false" client-requires-ssl="false"/>
</subsystem>
<subsystem xmlns="urn:jboss:domain:jsr77:1.0"/>
<subsystem xmlns="urn:jboss:domain:messaging-activemq:7.0">
   </lots of configs>
</subsystem>
<interfaces>
   <interface name="unsecure">
      <inet-address value="${jboss.bind.address.unsecure:127.0.0.1}"/>
   </interface>
</interfaces>
<socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
   <socket-binding name="iiop" interface="unsecure" port="3528"/>
   <socket-binding name="iiop-ssl" interface="unsecure" port="3529"/>
</socket-binding-group>

Ok, so we have jsr77, activemq and iiop. Closer, but not satisfying...

Question 1.

How can I have different JSR345 or JSR352 implementation without any mention on xml configuration?

Question 2.

jsr77 says:

The Specification proposes a standard management model for exposing and accessing the management information, operations, and parameters of the Java 2 Platform, Enterprise Edition components.

What jsr77 impacts on WildFly?

Question 3.

Those extensions references a lot of dependencies modules. How can I track what is effectively disable in standalone.xml?

Question 4.

How can I disable activemq or iiop but stays closer to full profile?

Thanks in advance!
