My experience over the last six months to a year has been more positive -- I'm seeing more large industry schemas, and they _are_ conformant, and I'm seeing fewer "Processor X and Processor Y disagree" messages (with one exception, see below), and most of those are on what everyone involved agree are corner cases. So my feeling is that the corner has been turned on interop -- of course the new release of the test collection will enable us to quantify this a bit better. There is one big, embarrassing, counter-example, in the form of a low-cost, widely-used tool which does not do very well at enforcing conformance. As far as I can tell serious W3C XML Schema users quickly learn they can't trust it, and back up its apparently admirable UI with another validator for conformance checking (I say 'apparent' because I've never used said tool). Gresham's law is always a problem :-(. ht -- Henry S.
