Mike responses in-line below Also note property mis-spelling as dfdl:binaryVirtualDecimalPoint in section 13.7.1.1.

SMH: It's also shown for 'binary' and IBM DFDL implements this. (Note: doesn't even allow for zoned as this is 'binaryDecimal....", and zoned is considered text). SMH: Correct. Zoned is text as you say, so VDP is provided by the 'V' character. Section 13.7.1.1 explicitly states this property can be used with non-base-10 representations to scale the value. While the functionality in 13.7.1.1 could be useful to people, I believe the intent of this property was to support virtual decimal points, which is, in my experience, a COBOL-oriented feature used with base-10 representations (zoned, text, or packed/bcd). In DFDL v1.0, zoned is considered textual, so this property doesn't apply to zoned numbers. That leaves only the packed/bcd representations. I suggest these changes: 1) language in 13.7.1.1 should be revised to avoid requiring this property to apply to binaryNumberRep='binary' (aka twos-complement or unsigned binary) integers. SMH: No, see response above 2) The definition of the property should explicitly state it applied only to base 10 binary (aka packed/bcd) representations. SMH: No, as a corollary.
