Indeed, it is function findWithElemPath
that is defined in terms of this function, findWithElemPathEntry
, and not
the other way around.

API for elements as containers of elements, each having a name and possible attributes, as well as an "element path" from the root element. See PathAwareElemLike.
This purely abstract query API trait leaves the implementation completely open. For example, an implementation backed by an XML database would not use the
implementation, for reasons of efficiency.PathAwareElemLike
