Formal correspondence with her-
In formal Danish, you can replace a preposition + pronoun (like "with this" or "in it") by combining her (here) or der (there) with a preposition.

| We hereby attach the file. | Vi vedhæfter hermed filen. |
| I hereby send you the statement. | Hermed sender jeg erklæringen til jer. |
Similarly, heri means "herein" or "in this document".

Referring back with der-
