[DFDL-WG] Actions 279, 293, 314, 306 - Updated new Errata 5.60-5.63 for review

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: 
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). 
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, a
ction 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:

https://redmine.ogf.org/dmsf_files/13384?download=

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