Under construction
Some of the official errata in the DFDL specification are supported in Daffodil.
Keep in mind that Daffodil does not implement (currently) an unparser, so when the tables below indicate 'Yes' for support of an erratum, that means it is supported in the Daffodil parser.
Erratum | Supported | Notes | ||||||||||||||||||||||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
3.1 | Yes | |||||||||||||||||||||||||||||||||||||||||
3.2 | Yes | dfdl:outputValueCalc not supported (because unparsing not supported) | ||||||||||||||||||||||||||||||||||||||||
3.3 | Yes | |||||||||||||||||||||||||||||||||||||||||
3.4 | No | recoverableError not supported | ||||||||||||||||||||||||||||||||||||||||
3.5 | Yes | |||||||||||||||||||||||||||||||||||||||||
3.6 | No | Not supported | ||||||||||||||||||||||||||||||||||||||||
3.7 | No | unicodeByteOrderMark not supported. Use UTF-16BE or UTF-16LE, UTF-32BE or UTF-32LE | ||||||||||||||||||||||||||||||||||||||||
3.8 | No | Properties for some unimplemented features are ignored. No warning or error. | ||||||||||||||||||||||||||||||||||||||||
3.9 | Partially | dfdl:lengthKind 'pattern' is limited to only text. Recursively children are not checked for text and same encoding. | ||||||||||||||||||||||||||||||||||||||||
3.10 | Yes | |||||||||||||||||||||||||||||||||||||||||
3.11 | Yes | dfdl:occursCountKind 'implicit' and 'parsed' are supported. | ||||||||||||||||||||||||||||||||||||||||
3.12 | No | Validation is not supported. | ||||||||||||||||||||||||||||||||||||||||
3.13 | No | The property encodingErrorPolicy is not supported. The behaviour in the presence of decode errors is undetermined. | ||||||||||||||||||||||||||||||||||||||||
3.14 | Yes | Both old (deprecated) property is supported along with the new one. | ||||||||||||||||||||||||||||||||||||||||
3.15 | No | The new properties elementID and choiceBranchRef are not supported. | ||||||||||||||||||||||||||||||||||||||||
3.16 | Partially | The removed property documentFinalSeparatorCanBeMissing is not accepted. However, documentFinalTerminatorCanBeMissing is not supported. | ||||||||||||||||||||||||||||||||||||||||
3.17 | See sub table |
| ||||||||||||||||||||||||||||||||||||||||
3.18 | Yes | Functions use the new names. (The rest of this erratum is not observable in behavior of the system.) | ||||||||||||||||||||||||||||||||||||||||
3.19 | No | Default values are not consistently evaluated. Constants can be used, but reference between default value expressions may cause a schema definition error. | ||||||||||||||||||||||||||||||||||||||||
3.20 | No | dfdl:newVariableInstance not supported | ||||||||||||||||||||||||||||||||||||||||
3.21 | Partial | New placement restrictions are not checked. External variables are not supported. | ||||||||||||||||||||||||||||||||||||||||
3.22 | No | (This erratum is not behavioral, however, it is relevant that single-assignment checking of variables is currently not consistently performed.) | ||||||||||||||||||||||||||||||||||||||||
3.23 | Yes | |||||||||||||||||||||||||||||||||||||||||
3.24 | Yes | |||||||||||||||||||||||||||||||||||||||||
3.25 | Partial | dfdl:newVariableInstance is not supported. | ||||||||||||||||||||||||||||||||||||||||
3.26 | No | Default values not supported. |
