| 11 | * TODO: |
| 12 | * - when types are redefined in includes, check that all |
| 13 | * types in the redef list are equal |
| 14 | * -> need a type equality operation. |
| 15 | * - if we don't intend to use the schema for schemas, we |
| 16 | * need to validate all schema attributes (ref, type, name) |
| 17 | * against their types. |
| 18 | * - Eliminate item creation for: ?? |
| 19 | * |
| 20 | * URGENT TODO: |
| 21 | * - For xsi-driven schema acquisition, augment the IDCs after every |
| 22 | * acquisition episode (xmlSchemaAugmentIDC). |
| 23 | * |
| 24 | * NOTES: |
| 25 | * - Elimated item creation for: <restriction>, <extension>, |
| 26 | * <simpleContent>, <complexContent>, <list>, <union> |
| 27 | * |
| 28 | * PROBLEMS: |
| 29 | * - http://lists.w3.org/Archives/Public/www-xml-schema-comments/2005JulSep/0337.html |
| 30 | * IDC XPath expression and chameleon includes: the targetNamespace is changed, so |
| 31 | * XPath will have trouble to resolve to this namespace, since not known. |
| 32 | * |
| 33 | * |
| 34 | * CONSTRAINTS: |
| 35 | * |
| 36 | * Schema Component Constraint: |
| 37 | * All Group Limited (cos-all-limited) |
| 38 | * Status: complete |
| 39 | * (1.2) |
| 40 | * In xmlSchemaGroupDefReferenceTermFixup() and |
| 41 | * (2) |
| 42 | * In xmlSchemaParseModelGroup() |
| 43 | * TODO: Actually this should go to component-level checks, |
| 44 | * but is done here due to performance. Move it to an other layer |
| 45 | * is schema construction via an API is implemented. |
