Thanks Mike.  Here are my comments:

5.60 Clarifications of Choice Branch Selection when Defaulting (Action 279)

I think it is clearer to reword & restructure the first paragraph in 15.1.3 so that it refers to 9.4.3.2.  The second paragraph should be dropped, it is not adding anything.

"On unparsing there is the question of how the unparser identifies the appropriate schema choice branch corresponding to the data in the Infoset. Note that the Root of the Branch for one or more branches could be a sequence or a choice. The selection of the choice branch to unparse is as follows:
  1. The element in the Infoset is used to search the choice branches in the schema, in schema definition order, but without looking inside any complex elements. If the element occurs in a branch, then that branch is selected and if subsequently a processing error occurs, this selection is not revisited (that is, there is no backtracking).
  2. If the element in the Infoset does not occur in any branch, then there must exist a choice branch which is capable of being defaulted, as described by Section 9.4.3.2. If no such branch exists it is a processing error.
If there is no element in the Infoset, then there must exist a choice branch which is capable of being defaulted, as described by Section 9.4.3.2. If no such branch exists it is a processing error."

I don't think the additional paragraph is needed for 9.4.3.2. However, action 279 stated that Section 9.4.3.2 was deficient as it does not mention local groups.  Maybe we could add at the end...

"Any local groups encountered are handled by descending into the group and applying the above rules."

5.63 New property emptyElementParsePolicy (Action 306)

Need to add the property to section 22.1.

Ok, I created the trackers, they're just "see erratum 5.60" etc. but they're there just for due process.

I created 4 new errata in the errata document corresponding to Actions 279, 293, 314, and 306.

I skipped the route of creating trackers first - just to reduce the number of steps.

The updated errata document for review has been uploaded to redmine here:

I also have added numerous formatting related change items to the tracker for minor/typographical changes here:
