What does "supported by accessible user agents" mean?

While trying to read WCAG 2.0 to see if I had any remarks on it I came  
accross the sentence "It is possible to conform to WCAG 2.0 using both W3C  
and non-W3C technologies, as long as they are supported by accessible user  

What exactly does "supported" mean here? Does it mean that the user agent  
is conforming according to the conformance criterea of the respective  
technology? Because if that is the case WCAG 2.0 would be quite useless  
taken into account that most software does not have fully conforming
