Add data-role or other attributes to container elements

Hi - I'm trying to use semantic views to make a view for jquery mobile. jqm uses data-role and other data attributes in the elements to identify how it should display things. So I'd like to change the ul style, for instance, to be < ul data-role="listview" > instead of just < ul > - I see that I can put a class on the ul, but I don't see any way to add any other attributes. I could imagine a scenario where I might need an id, for instance... Is osmething like this possible?
