// The bug concerns the COPY operation of some attributes of a non-self-contained label.
// The attributes making the label non-self-contained are not involved by the operation.
// Therefore, these attributes shouldn't be considered by the COPY mechanism and
// the label should be considered as a self-contained.
// Correction of the bug consists of ignoring the attributes not involved by the COPY operation.
