I certainly can't see a case for it.
What are the specific use cases that require anyone to have a date
field whose value can be a machine-readable representation of "10
years"? E.g. where one would need to do something like this, where the
value of 'bar' is expected to be any EDTF date representation:
<foo bar="[insert EDTF expression of '10 years']"/>
... rather than to simply do it modeling (not the value, but the key/attribute):
<foo year-span="10"/>
...?

So I'd call representing "the 1960s" out of scope then. Are we all on
the same page with this, or not?
