It gave...

Yes, I have noted that... ;^)

Yes, I am learning that XYRS is not in any way a standard. Are there
any conventions for how to interpret the data? Where is the 0,0
point assumed? What is the 0 degree reference? Which *way* does the
rotation go, CW or CCW? I guess you can get the 0,0 reference from
the Gerbers, but how does the assembly house translate this to the
board? I assume that again, there is no standard.

I'm going over there now to discuss this with them. It resulted in
my pretty, pretty prototypes being mangled by hand unsoldering and
resoldering... :^(
I'm off! I'll let you know what I find.
