> It is sometime not very clever to activate dynamic anchoring in order to change the matching behavior, because the selection of the anchoring rule elements depends on the elements in the annoation index, and is therefore not predictable when the rules are written. I think it is not achievable to ensure the same matching behavior independently from the current matching direction, because of the greedyelements. If the user wants to take advantage of other matching directions, then a manual selection of the anchoring rule elements would be a good solution. We need to find a nice syntax for this extension. It could look like:
> {noformat}
> // match everthing from the last period to the last token...
> PERIOD # 'LastToken; // ' indicates the anchoring element
> {noformat}
> Here, the rule would start with the LastToken and then will search for the next PERIOD.
