Indeed, for example, is eq 3.2.1  the first equation of the second section
of chapter three, or the first equation of the second subsection of section
three of the current chapter, or the first equation of the second
subsubsection of subsection three of the current section, or ...?

In other words, the same depth of sub...subsections has to be maintained
throughout - hard to do.
