I am in favor of revisiting the decision we made, for the following reasons:

* Ease of implementation, as mentioned by Norm.
* Ease of use for the pipeline author: people are IMHO more familiar
with XPath expressions than match expressions.
* Using XPath expression does not prevent pipeline authors from doing
anything they can do now with match expressions.
