aoqi@0 | 38 | * This filter detects the use of incorrect JAXB namespace URI. |
aoqi@0 | 39 | * |
aoqi@0 | 40 | * When the binding compiler looks at a schema file, it always look |
aoqi@0 | 41 | * for the namespace URI of the elements (which is correct, BTW.) |
aoqi@0 | 42 | * |
aoqi@0 | 43 | * <p> |
aoqi@0 | 44 | * However, one unfortunate downside of this philosophically correct |
aoqi@0 | 45 | * behavior is that there is no provision or safety check when an user |
aoqi@0 | 46 | * misspelled JAXB binding customization namespace. |
aoqi@0 | 47 | * |
aoqi@0 | 48 | * <p> |
aoqi@0 | 49 | * This checker inspects the input document and look for the use of the |
aoqi@0 | 50 | * prefix "jaxb". If the document doesn't associate any prefix to the |
aoqi@0 | 51 | * JAXB customization URI and if it does associate the jaxb prefix, |
aoqi@0 | 52 | * this checker will issue a warning. |
aoqi@0 | 53 | * |
aoqi@0 | 54 | * <p> |
aoqi@0 | 55 | * This warning can happen to completely correct schema (because |
aoqi@0 | 56 | * nothing prevents you from using the prefix "jaxb" for other purpose |
aoqi@0 | 57 | * while using a JAXB compiler on the same schema) but in practice |
aoqi@0 | 58 | * this would be quite unlikely. |
aoqi@0 | 59 | * |
aoqi@0 | 60 | * <p> |
aoqi@0 | 61 | * This justifies the use of this filter. |
