specificity, user style sheets and SVG


How can a user style sheet override authors use of style attribute  
with ID?
that is a single style sheet to override the general use of ID by  
authors across the web.

in particular how could one override the general case similar to:
#symbol3Text a {fill:green;}
and provide visual changes for pseudo classes hover etc...


also and more generally within SVG

Is there an intention within SVG1.1 that at least with text the user  
might control the appearance for links, visited, hover, focused etc
are there examples?

I found this unintelligible:
6.17 User agent style sheet
