Can someone point me to documentation about making an ordered list starting with a number other than '1.' so that when it is exported to html the numbers will be sequential using the numbers I put in the list?

E.g., instead of a list as follows:

BEGINNING OF LIST
1. Some text
2. Some text
3. Some text
END OF LIST

I would like the list to start as follows:

BEGINNING OF LIST
27. Some text
28. Some text
29. Some text
END OF LIST

Thank you,
Shawn
