You could always keep a local svn repository and commit to that, if you really wanted to commit without connectivity. But in practice most people don't, as evidenced by the success of github, which grinds many development processes to a halt every time it is down.

It also ignores svk, which is (was?) a popular add-on to svn, which provided a convenient way to do this and replay all the commits to the central svn repository when connectivity allowed.
