From Item5916:
Raf, the
isempty operator applies only to the %IF statement. If you implemented it in the TWiki::Query base class, then it would also be available to queries. This would affect both the implementation and the documentation, and there may be reasons you chose not to do this, but i thought I'd mention it anyway. -- CC
