I am trying to use the may not split role like shown below but it does not appear to have any effect on what happens when the user presses enter in the middle of the title. Is there anything I am doing wrong?
<x:node match="class('topic/title')">
<x:name xml:lang="en">Title</x:name>
<x:role>may-not-split</x:role>
</x:node>
What is the behavior you are trying to achieve, and what is the behavior you see at the moment?
The main purpose of the may-not-split role is not really to prevent split of the element itself, but to delegate the split to the parent element instead, splitting both the parent and the element itself in the end.
If you want to completely disable the ability to split an element, the best option is to use the events in our Javascript API and revert the user action that caused the event there. See our page on preventing structure changes for more information.
