Vertex groups come in a number of different formats. Typically the first vertex group entry is of format 0x40000002 and contains the actual vertex array.

Vertex group format 0x40000002:
Each mesh's primary vertex group contains an array of vertex component declaration objects, defining the order and parameters for each of a vertex's components.

Vertex formats:
Vertex formats with bone data support multiple bone assignment. In this case, the sum of all bone weights is 0x64.

Vertex format 0x28 (and possibly others) supports multiple bone assignment. In this case, the sum of all bone weights is 0x64.
Vertex components are stored as one of the above data types, and the vertex component declaration contains a multiplier that adapts the values to the float version which the game will use.
For example, color RGBA values are stored as bytes, and the multiplier converts them from 0-255 to 0-1.0, and position components using short values are normalized via the multiplier to take advantage of the entire short value range.
