Dynamics CRM 365 userlicensetype puzzle

Not sure how Microsoft is handling & maintaining this license attributes in Dynamics CRM 365. We all know that license is getting assigned in O365 portal then the system user will be enabled in Dynamics.

When I stumble with this Stack Overflow question  I really got confused. As caltype is a picklist & it can be queried from stringmap table, also the enum values are documented in here

Fetchxml query used:

<fetch>
  <entity name="stringmap" >
    <attribute name="attributevalue" />
    <attribute name="attributename" />
    <attribute name="value" />
    <filter type="and" >
      <condition attribute="objecttypecode" operator="eq" value="8" />
      <filter type="and" >
        <condition attribute="attributename" operator="eq" value="caltype" />
      </filter>
    </filter>
  </entity>
</fetch>

But there is another attribute userlicensetype which is just a whole number field. So no stringmap, no meaningful values. Surprisingly not documented. So I have created a github issue.

I went ahead & exported the users, then did some slice & dice gave me this data. But could not comprehend these combos. Puzzle is still unsolved!?
