what is the meaning of each source severity category?

To whom it may concern

Hi,

I can find fixlet messages that have a source severity saying like critical, important, moderate, or low.

The source severity has published by vender such as Microsoft in Patches for Windows Site.

But the problem is that some specific fixlet messages don’t have the severity. They only show us “Unspecified” or “N/A”.

Here is my question;

What is the meaning of “unspecified” and “N/A” here?

What is the difference between the two, “unspecified” and “N/A”?

Thank you in advance.
