Peter Klügl commented on UIMA-6045:
-----------------------------------
I'll postpone this improvement again since it is just too much work for the
effect regarding the current layout of the parser. The strategy how the type of
a expression is resolved during parsing needs to be changed. if the feature
expressions in argument are delegated to the specific expressions, then the
wrong type will win, e.g., boolean instead of string. If composed expressions
are defined on argument level, then a completely new expression needs to be
introduced, which is able to aggregate arbitrary expressions on demand.
