viva-camctl xml — dump a camera’s GenApi XML.
Every camera-specific bug found so far was diagnosed from the reporter’s
own XML, and until now the library offered no supported way to produce one:
the fetch existed but only behind common::open_camera, which builds a
nodemap first. That is exactly the step that fails on the cameras whose XML
we most need — the reporter of issue #45 was told camctl could dump it,
could not, and had to supply four other models instead.
So this command stops at the fetch. Nothing is parsed, so nothing about the document’s contents can make it fail.
