To summarise it a bit: 1. We don't support <redefine>s yet. 2. <any> with a namespace of "##other" does only work if minOccurs/maxOccurs both are 1 [1]. 3. We don't support ID/IDREF yet [2] - use identity-constraints instead 4. The complex content model cannot be built in some cases [3] 5. The subset of XPath for identity-constraints is not checked yet, so be careful what expressions you use 6. Complex type <restriction>s are not checked for being a valid restriction. I recommend using an other XS processor if you need a teacher for valid restrictions. 7. The data-type section seems to work pretty well, except for float and double values, where we don't support the whole range of values (extremely low/high values) We have still some failures in the W3C test suite, mostly on the MS side; many of the failures are due to the tests itself being broken, but some of them might reveal some new bugs. I'm already a bit burned out by looking at every single test and compare the results with Xerces and XSV - there are simply too many of them (about > 7K). The W3C schema test suite is currently under revision by the W3C people, so we should get more accurate/assured results soon. If you need exact knowledge of the missing parts, search for "TODO" in xmlschemas.c. Many of the TODOs should be internal, but some of them are directly related to missing parts in the spec.
