/**
* Allows to specify a 'logical or' condition to specify a match. This intended to be used with a
* safety mixin.
*
* For example if you specify ("lcn=yes", "rnc=yes", "ncn=yes") then the specifier will match if one
* of these tags matches.
*
* Background: If you would add 3 separate matches with a {@link BestMatchSpecifier} that would mean
* that a way that is matched with all of them would receive too high a safety value leading, as the
* mixin is applied several times.
*
* 'Logical or's are only implemented for mixins without wildcards.
