Description
Currently, the following query reveals that several datasets have an illegal default target feature:
SELECT d.did, d.name FROM `dataset` d WHERE default_target_attribute NOT IN (SELECT name FROM data_feature WHERE data_feature.did = d.did)
this should be checked when uploading a dataset.

Research direction
Start by locating the ARFF checker and the dataset-upload validation path, then compare their handling of column names with the reported query. The work is done when an upload with a default target attribute absent from the dataset's legal column names is detected and the checker reports it consistently.
