    <!--temperature control of the mounting (e.g. relevant when hot_mounting Al)
cleaning procedures
a descriptor of the shape of the specimen
borrow from NXlab_thermo_mechanical_processing to document the external
stimuli (eventually) applied during mounting
temperature, mechanical, magnetic, electro-magnetic, are externally
applied stimuli on the sample, can we use one master schema?
e.g. one can even store NXcg_polyhedron_set and NXcg_face_list_data_structure
instances to keep track of the geometry of specific instrument and how
the samples were arranged in these
key question is which steps has the sample experienced?-->
