> Hey Peter...
> I have two examples where rules using | and & presumably miss out matches.
> However, this may be cause by other steps of the execution process than these
> rule elements since I couldn't find a bug in ComposedRuleElement class.
> Hopefully, you can enlighten me on this. I used the Workbench to test this:
> * Example 1
> Text:
> {noformat}
> A B A B
> {noformat}
> Script:
> {noformat}
> DECLARE A, B, C;
> "A" {-> A};
> "B" {-> B};
> ((B A) | ("B" "A")){-> C} W;
> {noformat}
> I'd expect a C annotation on "B A" here, but it only outputs the A and B
> annotations from the first 2 rules. On the other hand, if I replace the |
> with &, it creates a C as exprected. That doesn't seem right. | should be a
> less strong condition.
> * Example 2
> Text (same):
> {noformat}
> A B A B
> {noformat}
> Script:
> {noformat}
> DECLARE A, B, C;
> "A" {-> A};
> "B" {-> B};
> ((B A) & ("B" "A")){-> C} @W;
> {noformat}
> Here, its the other way around, meaning that a C annotation is created using
> |, but not &. I don't see way either the direction or the use of &/| should
> make any difference in this case.
> Thanks,
> Michael

> Btw: Can I assign this issue myself and just unable to find the button for
> that or do I lack permission?
