Sub Byte Element

• Sub Byte Elements are values of type bool, uint2, or uint4, which require less than a byte for storage.
• All Sub Byte Elements are Unsigned (aka non-negative).
• Attributes store their values in arrays. Arrays of Sub Byte Elements are a multiple of 4 bytes long (DWORD) which each store 32 / NrOfBitsPerValue values per DWORD.
• All units of Sub Byte Element Values have a pre-defined cardinality of 2^NrBits, which cannot be overridden, their first value is 0.
• There is no extra undefined value indicator for Sub Byte Elements.
