Hi FAST community, thanks for your assistance... I don't see anywhere that delta encodings, such as ASCIIStringDelta are defined. This grammar from section 10 is not complete: stream ::= message* | block* block ::= BlockSize message+ message ::= segment segment ::= PresenceMap TemplateIdentifier? (field | segment)* field ::= integer | string | delta | ScaledNumber | ByteVector integer ::= UnsignedInteger | SignedInteger string ::= ASCIIString | UnicodeString delta ::= IntegerDelta | ScaledNumberDelta | ASCIIStringDelta | ByteVectorDelta Specifically, I'm looking for the delta encodings. ASCIIStringDelta, for example is referenced in 6.3.7.3: "The delta value is represented as an ASCII String Delta in the transfer encoding. The subtraction length of the delta specifies the number of characters to remove from the front or back of the base value. Characters are removed from the front when the subtraction length is negative. The string part of the delta value represents the characters to add to the same end of the base value as specified by the sign of the subtraction length." Specifically, is subtraction length a prefixed integer length, or is it the length of the delta string? More generally, though, where are these formally defined (the transfer encoding link in the basic user's guide is broken)?
