Uncertainty and Discriminators
There was quite a lot of overlap between the Discriminators document and the previous Resolving Uncertainty document so I merged the two together and incorporated Suman's and Steve's comment. It is a bit of a rushed job but should help the discussion. I didn't have time for examples.

With my comments and edits. This works for me. I added one thing of substance. Inductively, if a sequence group is known to exist, and that sequence group is required within an enclosing sequence group, then the enclosing sequence group is also known to exist. This lets these things cascade outward naturally by the implications of being required. I fixed typos like plurals and such. We have to decide about the term "component". I thought the term for "element or model group" was "item". On Wed, Jan 27, 2010 at 7:14 AM, Alan Powell <alan_powell@uk.ibm.com> wrote:

Alan,
This is where I am with discriminators. I won't have an opportunity to work on this again for a bit, and it's close, though not perfect. In particular, there's a numbered list of points here, and the order of those points is probably not right.
