[jira] [Commented] (DAFFODIL-1885) Initiators are not being inherited from parent choices

["Michael Beckerle (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DAFFODIL-1885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16347593#comment-16347593 ] 

Michael Beckerle commented on DAFFODIL-1885:
--------------------------------------------

You need a bigger example to illustrate what is going wrong here. Nothing inherits initiators other than from the default format.

I claim the above schema is equivalent to (removing group ref)
{code}
<xs:choice dfdl:initiatedContent="yes">
  <xs:choice dfdl:initiator="%#11;:"> <!-- allowed. Doesn't matter that this is itself a choice, it's a "thing" with an initiator to satisfy the dfdl:initiatedContent=yes of the enclosing choice --> 
      <xs:element name="elementWithInheritedInitiator"/> <!-- no initiator is defined nor needed to "inherit" anything --> 
      <xs:choice> <!-- degenerate choice of 1 thing. Can remove this choice. Did you want an optional element?  --> 
         <xs:element name="elementWithoutInheritedInitiator"/><!-- no initiator is defined nor needed --> 
      </xs:choice>
  </xs:choice>
 ... this is where the next thing that must have an initiator would appear
</xs:choice>
{code}
I can simplify the above to:
{code}
<xs:choice dfdl:initiatedContent="yes">
  <xs:sequence dfdl:initiator="%#11;:">
    <xs:choice>
       <xs:element name="elementWithInheritedInitiator"/>
       <xs:element name="elementWithoutInheritedInitiator"/>
    </xs:choice>
  </xs:sequence>
... more elements sequences or choices would go here.  All must have dfdl:initiator properties....
</xs:choice>
{code}
You see that the names of the inner elements no longer make sense. They're not children of the outer choice.

>             Project: Daffodil
>          Issue Type: Bug
>          Components: Compatibility, Front End
>    Affects Versions: 2.1.0

> This is a bug that is currently effecting the compatibility with the IBM4690-TLOG schema project.
> In the IBM4690-TLOG schemas there is a parent choice with dfdl:initiatedContent="yes" that contains groups of choices.  The child choices define an initiator, but the initiator does not seem to be getting passed down the the elements contained within the choice inside the child choice (3rd level choice), causing the following SDE:
> Schema Definition Error: Enclosing group has initiatedContent='yes', but initiator is not defined.
>  
> Here is a simplified schema as an example:
> {code:java}
> ...
> <xs:choice dfdl:initiatedContent="yes">
>   <xs:group ref="childChoice"/>
> </xs:choice>
> <xs:group name="childChoice">
>   <xs:choice dfdl:initiator="%#11;:">
>     <xs:element name="elementWithInheritedInitiator"/>
>     <xs:choice>
>       <xs:element name="elementWithoutInheritedInitiator"/>
>     </xs:choice>
>   </xs:choice.
> </xs:group>
> ...{code}
>
