Sound good to me, i have just work on fixing the get-update-detail in 
the yum backend. the current code will send


package_id	The package ID
updates		A list of package_id's that are to be updated
obsoletes	A list of package_id's that are to be obsoletes
url	A URL with more details on the update, e.g. a security advisory

a list of URLs separated by ';', it can be URLs to bugzilla reports, CVEs

restart_enum	A valid restart type, e.g. "system"
'none' or 'system'

update_text	The update text describing the update in a non-localised 
way. Newlines should be converted to ";" before printed.

It looks like there is problem in the frontend to convert the ';' back 
to newlines.

We could add the other parameters to the signal.

we use '\t' as a parameter separator and ';' as list element separator 
if a single parameter contains multiple values (or lines in a description)
So it should not be that hard.

the url could contain


<urltype> = (bugzilla|cve|other)
<href>	  =  The real URL
<urltext> = A decription to the url

I have fixed the yum backend so update severity is working

enhancement = low
bugfix = normal
security = security
