If l1 (e.g. gene) and l2 feature (e.g. mRNA) are missing for several CDS that must be collectively linked (one CDS several position in the EMBL file), the tool create one EMBL CDS feature per GFF CDS feature.
Would be nice to deal with that.
To deal with such case, currently we need to run agat_sp_gxf_to_gff.pl from AGAT to create the missing L1, L2 features.
