Here's my latest updates. As discussed I have reworked the 'Nils & Defaults on parsing/unparsing' sections. One question was thrown up. On parsing when a required complex element is missing, we add it to the infoset as long as applying default processing to its missing children does not cause an error. You will see I have used the phrase 'Missing element processing is applied to all child elements.' to cover this. But 'Missing element processing' as now spelled out in the same section includes 'nillable and empty string' processing when the child is simple. Does this apply here?

I did attempt to write out the dfdl:nilValueDelimiterPolicy and dfdl:emptyValueDelimiterPolicy options in full but it became unreadable hence the 'as controlled by' short cut.

I have only completed the parsing section so far which you should be able to review while I am on vacation. If someone would like to add the unparsing section that would be great. Note that the cross references are not correct.
