[DFDL-WG] Agenda for OGF DFDL WG call 13 January 2010- 13:00 UK (8:00 ET)

Tue Jan 12 11:19:57 CST 2010

1.   045  - Disciminators
Discussion with Stephanie 

2. Zero length elements
Review Steve H email

3. Difference between dfdl:lenghtKind= Delimited and endOfParent

'delimited' means the item is delimited by the item?s terminator (if 
specified) or an enclosing construct?s separator or the end of the 
enclosing construct designated by its known length or its terminator. 
 the only difference with dfdl:lentghKind='endOfParent' is that  the 
latter includes the 'end of the data stream' and applies to binary fields. 

We should either 
Add 'end of data stream' to delimited and remove 'endOfParent' 
Make 'endOfParent' be specifically for only  'end of data stream'

4. Go through remaining actions 

5 Draft 037 review

>From comments:

a  DFDL Subset of XML Schema   (TBD: need means for an implementation to 
indicate it is using non-standard extensions?)

b. Question whether infoset MUST be in schema order.  Request for 
'bitstream order'

c. Dealing with 'Grammar ambiguity' errors
