\begin{notebox}
When specifying multiple files, repeated XML sub-elements are not merged.
The sub-elements from files appearing later in the list will override those
elements from earlier files.
The sub-elements from files appearing later in the list will, in general,
override those elements from earlier files.
\medskip
For example, the \inlsh{NekMesh} utility will produce a default
\inltt{EXPANSIONS} element and blank \inltt{CONDITIONS} element. Specifying
a custom-written XML file containing these sections \emph{after} the
file produced by \inlsh{NekMesh} will override these defaults.
The exception to this rule is when an empty XML sub-element would override a
non-empty XML sub-element. In this case the empty XML sub-element will be
ignored. If the custom-written XML file containing \inltt{CONDITIONS} were
specified before the file produced by \inlsh{NEKMESH}, the empty
\inltt{CONDITIONS} tag in the latter file would be ignored.
