Re-applies templates to the current node in the current mode, considering only templates of lower import precedence than the one being instantiated, falling back to the built-in rule when none match. Threads the current mode and import precedence through the evaluation context, and moves the transformer runtime types into XSLTRuntime.swift (namespaced, via private aliases) to stay within the file-length and namespacing gates.
