But then I noticed that it also passes the context vars to the synchronous backround stuff, which is nice. Wonder why that's not the case in the stdlib, cause it would be nic

obspy.core.event.Pick(time=time, waveform_id=wid, phase_hint="P", evaluation_status="reported")

As suggested by some users, it would be good to support a new parameter parent.labels (TRUE/FALSE) for aas.data.frame applied to SDMX datasets, that would allow to enrich the dataset also with parent code labels. The code should generic enough:

• to manage parent hierarchies (not only the 1st parent code/label)
• to manage it for all potential codelists describing the dataset and having
