Similar...but getElementsByTagName only returns Element nodes by name where
XPath expressions are capable of returning all *core* node types, not just
element nodes. It really makes sense to have the API available on the Node
interface because relative expressions can be applied to all *core* node
types (element, attribute, text, comment, pi).

Yes, but it also exists in the Element interface (it's just in Document for
convenience). If this API is in the Node interface, it's available
everywhere.
