This is precisely what we cannot, IMHO, allow. I will agree with you
that SRW/U might well profit from a richer diagnostic structure -- but
that is all. The word "creative" looks nice and appealing sitting
there innocently like butter wouldn't melt in its mouth, but we all
need to remember that in this discussion, "creative" has the meaning
"sloppy, unpredictacle, non-interoperable".
And, by the way, the lesson of Z39.50 (the BIB-1 diagnostic set
vs. the Diag-1 diagnostic format) is surely that implementors want
_simpler_ diagnostics even when they are plainly inadequate. So I am
actually not even convinced that rich diagnostics in SRW are a good
idea. We already have one capability discovery mechanism (ZeeRex),
why add another redundant one?
