Maybe we just call it the accessibility tree?

AG: At the moment, this was superfluous, it was always null for a full tree. The only time it is not null is for the empty content tree, and for that tree it remains not null until the tree is destroyed. This will have a role when we implement some sort of feedback during updates of isolated subtrees or to avoid processing notifications while a subtree is being re-built. > > > Source/WebCore/accessibility/isolatedtree/AXIsolatedTree.cpp:181 > > + String percent = String::number(percentComplete) + "%"_s; > > + String title = AXProcessingPage() + " "_s + percent; > > I think using makeString will be more efficient here (less String > allocations). > > String title = makeString(AXProcessingPage(), " ", percentComplete, "%"); AG: we need both Strings, the percent and the title since they are used for different purposes. Also makeString and the operator+ resolve to invoking the same method tryMakeString in StringConcatenate.h, so I don't think there is significant advantage of one over the other performance wise, and + is a lot more readable. > > > Source/WebCore/accessibility/isolatedtree/AXIsolatedTree.cpp:190 > > + { AXPropertyName::TitleAttributeValue, title }, > > I think we can WTFMove(title) here.

Maybe we just call it the > accessibility tree? Removed "isolated" and left it as "accessibility tree".
