I don't see it as a temporary measure. VOTable is not supposed to
represent all data formats, FITS is a special case. From sec 2.3 of
the VOTable document:
"the transformation of FITS to VOTable is meant to be reversible"
The kind of data (though not metadata) which can be held in a VOTable
is by design compatible with the FITS binary table format, so that
requiring the possible storage of VOTable bulk data using a FITS
binary table does not introduce any additional limitations (put another
way, VOTable explicitly accepts the limitations of FITS binary tables
as far as pure data storage streams go).
