Types of Variations

1. mark + text: text can be added before or after existing labels, for example for the mark 'testmark' an extra label could be testmarks.

2. partial mark: substring of the mark with a minimum length of ½ of the total length (at least 3 characters), in other words a series of consecutive characters taken from one of the labels associated with the mark which length is at least half of the length of the label with a minimum of 3 characters.
For the mark 'testmark' extra labels 'test', 'mark', 'testm' would be allowed but not 'es' (too short) or 'tmark' (not consecutive).

3. similar to mark: characters are replaced by similar looking ones, like o and 0, accented and non-accented etc. A maximum ¼ of the total length rounded up is allowed to be replaced, based on a fixed list.
For example for mark 'coocoo' the maximum of replacement characters is 2, extra labels 'c00coo' and c0oc0o' would be allowed.
