EBU Single Rulebook Q&A 5 November 2013 2013_506 Definition of liquidity facility

Would it be acceptable from a regulatory point of view to use only the swingline portion of a facility (i.e. a loan to an entity to cover possible shortfalls from other debt commitments) as "liquidity facility"? Within Directive (EU) 36/2013 (CRD) and Regulation (EU) No 575/2013 (CRR) neither a definition nor a more detailed specification of "liquidity facilities" currently exists.
