I would like to ask to remove section 12.3.1. Limitations on JTA Transactions (https://access.stage.redhat.com/documentation/en/red-hat-jboss-enterprise-application-platform/version-7.0.beta/configuration-guide/#limitations_on_jta_transactions) as this section is misleading and does not give any relevant information to user.
That's in configuration guide.

I would like ask for the same change (meaning removing a chapter referencing this topic) from Development guide as well.
There is in chapter 11.2.11. About Distributed Transactions (n_2272823_development-guide_version_7.0_edition_1.0_release_0-revision_7907723) NOTE

Note
JTA transactions in which context is distributed through remote EJB
calls are not fully transaction distribution aware across multiple
instances of JBoss EAP 7. This works for simple scenarios where one
server calls another server. However, if there are multiple servers
connecting to the transaction distribution, context propagation is not
completely safe.

That would be fine to be removed as well.

The transactional ejb call from server to server should be covered in Development EJB Guide (JBEAP-3306).
