funny, you answered yes to a choice!  I was asking if you think the
mount point shows up as a node in the data tree, i.e., as shown in the
example in
https://tools.ietf.org/html/draft-ietf-rtgwg-ni-model-03#appendix-B.1?

from my perspective and my co-authors in the RTG area using schema
mount, we've never heard of a (filesystem) mount point that doesn't show
in the (directory) structure and this is the mental analogue we've been
assuming. Since there never was an explicit example/discussion or text
to dissuade us of this, this disconnect was never noticed.  Certainly
this needs to be explicit in the document (either way). The following
change could be made to the schema mount draft (at a minimum):
