—???? a textual data format based on an XML schema definition that is capable of holding the same information as the tagged binary format, and

—???? an on-card biometric comparison format based on extensible TLV encoding;

—???? on-card biometric comparison parameters based on extensible TLV encoding for constructing valid probe data in the on-card biometric comparison format;

—???? examples of data record contents;

—???? application-specific requirements, recommendations and best practices in determining minutiae location, direction and type; and
