Repository administrators can edit the historical contents of files by using "svnadmin dump"
to create a single-file representation of the repository, then use a dumpfile editing tool
to make changes to it, then use "svnadmin load" to load that file into a new repository.

This is not done in the normal course of using your repository. This is done in emergency
situations, such as: someone committed an enormous file to the repository and you need to
remove it to free up server disk space; or someone committed a password or other secret information
that cannot stay there. Sometimes, this is used to try to recover a corrupted repository.

Repository administrators can allow users to edit revision metadata, such as the author, date,
time, and log message of a commit, by creating a pre-revprop-change hook. This is surely described
in the svnbook.
