[DFDL-WG] Spec erratum in tables 18 and 20

[Steve Hanson]

Correction to tables below - only xs:dateTime can have binaryCalendarRep 
'binarySeconds' or 'binaryMilliseconds'.


Type
Length
text
binary
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

Decimal, Integer, nonNegativeInteger

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.

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.
