The "position" statement, which is optional, takes as an argument a non-negative integer value that specifies the bit's position.
Java mapping
Container BitSet is used to store bits during code generation.

Binary
Overview
The binary built-in type represents any binary data, i.e., a sequence
of sequence of octets.
A binary can be restricted with the "length" statement. The length of a binary value is the number of octets it
containsit contains.
Binary values are encoded with the base64 encoding scheme .
Java mapping
Byte array is used to store decoded binary during code generation.
