It wouldn't hurt to mention the types of things that could be stored, without
using keywords, as a guide to implementors. IF you describe the reults needed,
implementers will come back asking what kind of things to store.  I think
Greg was just pointing out that the current text should be softened, explaining
that the things in the list are examples of what could be stored ...
