No such thing as a "fATPL licence." Suggest you read JAR-FCL 1 or 2 as appropriate, if your question pertains to JAA licences.
JAR–FCL 1.001 (amdt 7) defines cross-country as "A flight between a point of departure and a point of arrival following a pre –planned route using standard navigation procedures."
JAR-FCL 1 Amendments 1-5 offer no definition. UK-granted JAA licences conform to only as far as Amdt. 5.
