| String | The XSD maxlength facet gives length in characters, but this is also the length in bytes. (See note below: character set encoding must be single-byte.) Multply by 8 to get number of bits. | Not applicable | |
| Float | Not allowed | 32 bits | |
| Double | Not allowed | 64 bits | |
| Decimal, Integer, nonNegativeInteger | Not allowed |
packed decimal: Not allowed
| binary: Not allowed |
| Long, UnsignedLong | Not allowed | binary: 64 bits | |
| Int, UnsignedInt | Not allowed | binary: 32 bits | |
| Short, UnsignedShort | Not allowed | binary: 16 bits | |
| Byte, UnsignedByte | Not allowed | binary: 8 bits | |
| DateTime | Not allowed | binarySeconds: 32 bits, binaryMilliseconds: 64 bits. | |
| Date | Not allowed | binarySeconds, binaryMilliseconds: Not applicable | |
| Time | Not allowed | binarySeconds, binaryMilliseconds: Not applicable | |
| Boolean | Length of longest of dfdl:textBooleanTrueRep and dfdl:textBooleanFalseRep values | 32 bits | |
| HexBinary | Not applicable | The XSD maxLength facet gives the length in bytes. Multiply by 8 to convert to number of bits. | |

| Decimal, Integer, NonNegativeInteger | Compute the minimum number of bytes to represent the value (per dfdl:binaryNumberRep) and sign (if applicable). Multiply by 8 for number of bits. | |

| Compute the number of bytes in the infoset value padded to the value of the XSD minLength facet (which gives minimum length in bytes) using dfdl:fillByte if necessary. This gives the unparse length in bytes. Multiply by 8 for the number of bits. | |
