> There are a number of data representations DFDL cannot handle because it cannot manipulate numbers with sufficient flexibility in expressions.
> We need AND, OR, NOT, maybe XOR, and shift left, shift right, and probably arithmetic shift right (which does sign-extension of signed numbers). We should add functions for the whole set of them.
> On signed numbers with specific sizes (long, int, short, byte) these should behave as if the data was binary in 2s complement representation, i.e., as if the most-significant-bit was playing the role of 2s complement sign.
> These operations should all be undefined (Schema Def Error) on decimal, integer, and non-negative integer values, as well as float and double.
> Specifically, these operations are defined on long and its subtypes, and unsignedLong and its subtypes only.
