[DataList Ordered] Change start index?

[Daedin]

Hello,

Is there a way, using the ordered datalist, to start at an index different from 1? E.g., build a list that looks like:
5. First item
6. Second item
etc.

The HTML <OL> tag seems to support a "start" attribute, but I can't seem to find an equivalent for p:datalist.

Is this possible?

Thanks for your time,
