All 

Latest draft of the nils and default document incorporating comments from 
last week. 

As you will see I have been having problems with bulleted lists in word 
which are still not correct but I assume I can fix for the spec.

Hi Alan - were you going to take the updates forward, or did you want me 
to make some changes first? 

Reviewed Steve's updates to the parsing and unparsing rules. 
- it might be possible to simplify the nil processing in the rules by 
having a defintion up front. 
-  'nil indicator set' need a definition 
- Discussion about whether 'usNilForDefaults' could be replaced by some 
way of defining a literal, out of band value for the default. 
- 'value' used when should be 'output value' 
- dfdl:emptyValueDelimietrPolicy description should be moved from 
defaulting section to initiator section. 
- 'text markup' used in section 14.2 of spec   

Regards

Re: [DFDL-WG] Fw:  Fw: Action 086 Nils and Default processing

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?

Hi Alan 

I've updated the document and added some comments. Still quite a bit to 
discuss.

All   

I have added unparsing and corrected some of the existing information in 
this latest version.   

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.   

Links still don't work

All   

Attached is an updated version of the nils and defaults sections of the 
specification. 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.
