I have a case where I recently had to use "validate-except" because of
a domain (not mine) whose external view is signed but not the internal
view; my resolver gets the internal view for that zone.

Can someone enlighten me as to why "DNSSEC was designed for external
zones", and under what circumstances it makes sense to *not* sign an
internal view?  It seems to me that it would be most consistent to
sign both external and internal views.
