It was suggested in Barcelona (by Eric?) that the overview document (part
0) include the use-cases referred to by other parts. I'm prepared to
capture these as part of that document.

I suppose there are maintenance issues here ... is part 0 ever finished if
not all of the other parts are not yet finished? ... should we retrofit
use-cases for the parts that are complete or close to complete (RELAX-NG
and Schematron)?

p.s. when using the noun, should I be hyphenating it to "use-cases" or just
writing "use cases"? I'm assuming the hyphen is required otherwise the
adjective/verb distinction of "use" is ambiguous.
