Hello :Regarding the vulnerability

[darshan na]

 Hi ,
I am student at one of the German Universtiy and i had a task of
Benchmarking the Vulenrability Providers based on the features they provide
and ,its really nice that you provide vulnerablity information in xml format
and this is really very useful to parse this information for analysis
i was checking your website where advisiories are present and i could not
find any risk level alloted to the vulnerability
It is difficult to analyse them without that , I just wanted to know is
there any particular reason for this
Thank you and
Best regards
