William,

I'm not sure.  There has been recent work to support Xerces 3.0,
so I'm surprised.

I didn't even know we had a grass test suite entry.  I don't
know what is happening here.

Yes, I've seen this sort of problem from time to time.  There
seems to be problems extracting the pseudo-geotiff-tags from
some mrsid files, though repeated efforts to resolve this
issue have failed.  What version of the mrsid sdk are you using?
I haven't run into this for a while myself.

I have also seen the image results come back with such modest,
but statistically significant differences.  I have no way to
address this though.

This is an autotest problem, and will be resolved when I upload
the fixed autotest.  It may be disregarded for now.
