CSSF
1. Overview & Version History
This technical guidance, updated to Version 1.7 in July 2024, builds on previous iterations to reflect evolving ESMA rules and CSSF procedures. Key changes include:

AIF reporting file (AIFMD_DATAIF_V1.n.xsd)
All text fields must be completed in English. Specific Luxembourg implementation details apply—e.g., province code “LU”, and the AIFM National Code formatted asAfollowed by eight digits with leading zeros.
3. Transmission Methods
