Thank you for your time.
The DOM specification provides "DOM features"[1] as a mean to 
extend the DOM with custom informations and methods, so that you 
can query a node at runtime if it supports a certain "feature". 
If it does, it will return you an interface that provides access 
to those infos and methods (usually that interface is just a 
dynamic cast of the object itself, but it is not mandatory). For 
example, an implementation may provide methods to modify SVG 
nodes in a more meaningful way than dealing directly with parents 
and siblings. You would access these extra methods using 
getFeature("SVG"). The W3C itself maintains a long list of such 
optional extensions [2].
