The perf penalty of xml:base is basically that we have to dynamically construct a URL from bottom to top along the tree whenever we need a base URL of an element. And since this URL may be constructed dynamically, the caller would have to hold a strong reference to it, and thus an additional refcount manipulation. So a URL not dynamically generated would be enough to avoid that penalty.
I assume this means that the Get/SetExplicitBaseURI API on nsINode is still OK?
