Since there is a group working on a database abstraction layer, this 
definately belongs there.

The first option above seems to be the most clear-cut. You should 
consider what sort of versioning you're looking for. Should it be 
reversible?

If I have this page:

Headline: abc
Text: defghi
Version: 2

and I add

Headline: abc
Text: defghi
Text: jkl

it becomes

Version: 3

If I were to remove the last text element again, thus reverting the 
change I just made, what should the version number be then? 2 or 4?

Michael.
