The AdditionalMapping option defines the additional mapping rule for the Profile by applying Transformer's in sequence.

The Disallow option further restricts a Profile's allowed characters beyond what is disallowed by the underlying string class.

The FoldCase option defines a Profile's case mapping rule.

The LowerCase option defines a Profile's case mapping rule.

NewFreeform creates a new PRECIS profile based on the Freeform string class.

The Norm option defines a Profile's normalization rule.

UnicodeVersion is the Unicode version from which the tables in this package are derived.

The BidiRule option causes the Bidi Rule defined in RFC 5893 to be applied.

The DisallowEmpty option causes the enforcement step to return an error if the resulting string would be empty.

The FoldWidth option causes the profile to map non-canonical wide and narrow variants to their decomposition mapping.

The IgnoreCase option causes the profile to perform a case insensitive comparison during the PRECIS comparison step.
