Make exceptions more explicit?

if hasattr(md, 'dataquality'):
    _set(context, recobj, 'pycsw:Degree', ','.join(md.dataquality.conformancedegree))
    _set(context, recobj, 'pycsw:Lineage', md.dataquality.lineage)
    _set(context, recobj, 'pycsw:SpecificationTitle', md.dataquality.specificationtitle)
    try:
        _set(context, recobj, 'pycsw:SpecificationDate', md.dataquality.specificationDate[0])
    except IndexError:
        LOGGER.debug('No specification date')

indexerror is not thrown if element does not exist, not sure when it is thrown
replaced it for normal exception, then logging the exception, was that the idea?
