API version format:
MMmmr_k 
Where "MM" is the major version, "mm" is the 
minor version and "r" is the revision. 
'M' and 'm' and 'k' are decimal digit from 0 to 9, 
while 'r' is an alphabetic. 
EX: 0302b_1 => Major version = 03, minor 
version = 02, revision = b, platform = 1 
The 4 integer numbers are WebAPI version, we 
use short name: [httpversion] for it in this 
document. 
The 5th character is model-based version for 
API bug-fix and it's default to "a". 
Ex: If some APIs in a model does not follow the 
API definition of 0301a_1, we will fix them and 
change this API value to 0301b_1.
