Creates a new string pattern type with the specified name, if it does not already exist.

@param  name      The name of the string pattern type to create.
@param  maxLength The maximum length of instances of the type, may be zero or less for no maximum.
@param  pattern   A regular expression that instances must match, or <tt>null</tt> for no pattern.

@return A new string pattern type.

@throws IllegalArgumentException If min is not less than or equal to max, or the named type already exists.
Creates a new string pattern type with the specified name if it does not already exist .
