We’d like to extend the screen condition for UI action in following way. A new child element should be introduced - most likely again ScreenSection condition, but the offered selection should also contain possible
SectionLevelPlugin model elements (in other words
SectionLevelPlugin). When resolving the availability the relation between screen condition and screen section condition is
AND. If there are multiple screen section conditions the resulting expression should be `screen condition AND (screen section condition 1 OR screen section condition 2).
- there is no possibility to limit usage of the UI action to a section plugin
- extend expressivity for conditions on screen level
