Re: No other way of handling missing values?

If only the last step in the chain can be missing (`perProductYn`),
then you don't need all that (...). And as Andy said, you could use
`exp!default == exp`. You can also use `exp! == exp` as `"" != "Y"`.
So at the end you end up with:

  <#if c.royaltyTerms.OffsetLimit.perProductYn! == "Y">
