DDSXTY14 — Refine issue resolutions

Issue DDSXTY14-41 adds some logic on how to handle Key members where the member type is unkeyed.

It says that nested members that are arrays/maps/sequences are not considered part of the container's key

It says optional and must_unsertand=false are considered part of the container key type.

We should revise this to make sure it is more consistent with what the @key annotation allows and also match what vendors are doing.

On DDSXTY14-94. Modify the resolution per the comment:
Replace "The for the Dynamic Language Binding" with "The Dynamic Language Binding"
