Emission lines relevant when :ref:`mode &lt;/NXxas_new/ENTRY/mode-field&gt;` is
`fluorescence yield` or `herfd`.

The emission lines are described as a list of names of the form
*"INITIAL-FINAL"* where *INITAL* and *FINAL* are electron levels
as listed for :ref:`here &lt;/NXxray_level/name-field&gt;`.
The emission lines are writen using the IUPAC notation, i.e. an
initial and final edge seprated by a hyphen.

TODO: Extend the enumeration to include all possible emission lines.
