Oh, I'm sorry for that :-/  But I'm sure there are many more commits to

Yes, there is, since the xpath expressions apply to the flow view data 
object (I prefer "view data" to "context object" as there are already 
too many "context" objects in Cocoon).

The main difference with DynamicSelectionList is that values are given 
in their object form, and not as Strings. DynamicSelectionList has a lot 
of code to convert the @value attribute format according to the 
selection list's convertor and the output Locale.

That's why FlowXPathSelectionList is so simple.

Well, awaiting your commit ;-)
