CDX Boolean Data Types

CDXBoolean:

In CDX files, an INT8 value representing True or Yes if non-zero, and False or No if zero.

In CDXML files, a enumerated value that may be either yes or no.

Note that this data type actually has a third implied value, 'unknown'. Since CDX and CDXML are both tagged formats, any given property may be omitted altogether from the file. A missing property of this type cannot be assumed to be either true or false.

CDXBooleanImplied:

In CDX files, an INT8 value representing True or Yes if present, and False or No if absent.

Note that properties of this type have zero length in CDX files: the only thing that matters is whether the property is or isn't present in the file. In contrast to the CDXBoolean data type (above), if a property of this type is missing from the CDX file, its value must be assumed to be False or No.

In CDXML files, a enumerated value that may be either yes or no.
