Enumerate between Sections

[Adolfo Pachón]

Hi all!!

I want to do this:

* I have 20  items.
* 10 in "Section 1", and the other 10 in "Section 2".
* I want to obtain this:

Section 1

    1. item 1 ....
    2. item 2 ....
    ...
    10. item 10 ....

Section 2

    11. item 11 ....
    12. item 12 ....
    ...
    20. item 20 ....


How can I do this?

Thanks.
