Now released, to CVS, in online webform version and downloadable exe. This reduces to four the number of unimplemented aspects of the Structures part of W3C XML Schema in XSV: 1) All groups aren't properly checked or enforced; 2) ID/IDREF isn't checked; 3) Identity constraints are compared as strings, not values; 4) All numeric exponents >100 are treated as 100. The first two are straight-forward but tedious -- SMOP. The third is hard, as it requires implementing lexical->value space conversion which is not always obvious. The fourth will never happen, it makes denial of service attacks too easy. From Datatypes, a lot of simple type enforcement is still missing, and will probably stay that way. . . There will soon be an erratum moving responsibility for enforcing ENTITY and ENTITIES to Structures, at which point the above count will rise to five :-( ht -- Henry S.
