Well yes, of course, the assumption is that the server advertises that it
understands MODS.

But the question is how do you declare an abstract index to correspond to an
element? The dc example has a bit of hand waving, I think.

When you say

<name set="dc">date</name>

you're referring to 'dc' as an *index* set, thus "date" refers to  the index
'date', but you're implying the *element* <date> (as far as I can interpret
the example) a reasonable implication because of the flatness of dc and the
correspondence of indexes to elements.

But  how would you declare the abstract index 'copyrightDate' and define it
so it maps to:
<mods><originInfo><copyrightDate>
