DOCIDDelta (variable)

...

Code (variable): Bit sequence for symbol corresponding to the document identifier. The size of this field MUST equal the value of the Length field in the corresponding CodingTableEntry element of the Coding table array in the ExtensionCompressionTablePage.

DOCIDDelta (variable): Uncompressed DocIDDelta value for the document identifier. This field only exists if Code field defines a special symbol. The size of this field MUST be 2 bytes if Code field defines the first special symbol for the category, or 4 bytes if the Code field defines a special symbol other than the first special symbol.
