Hi Joris,

  1. goes against the TIFF spec that says tag data must be self-contained and cannot include pointers to anywhere outside of that tag data.

Very true, but the TIFF specification is contradictory, and IFD's defined in the standard are allowed to violate this rule.

  1. is not a problem if you don't copy tags you don't fully know, like I recommended Anurag in the first place though he didn't seem to think that recomendation was worth considering.

True again, but I would never take my car to a mechanic who simply discards the parts he doesn't fully understand.

(I don't expect a response to this -- I'm just venting because this touches on some aspects of the TIFF specification which I find very unfortunate.)
