Steve Lawrence updated DAFFODIL-80:
-----------------------------------
Labels: (was: dev-verify)
Doing a quick grep, I cannot find any SDE's that mention recursive references.
So I suspect this is still not implemented. I've also created the following
basic recursive schema, which results in a stack overflow.
{code:xml}
<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:dfdl="http://www.ogf.org/dfdl/dfdl-1.0/";>
<xs:include
schemaLocation="org/apache/daffodil/xsd/DFDLGeneralFormat.dfdl.xsd" />
<xs:annotation>
<xs:appinfo source="http://www.ogf.org/dfdl/";>
<dfdl:format ref="GeneralFormat" />
</xs:appinfo>
</xs:annotation>
<xs:element name="recursive">
<xs:complexType>
<xs:sequence>
<xs:element name="field" type="xs:string" dfdl:lengthKind="explicit"
dfdl:length="1" />
<xs:element ref="recursive" minOccurs="0" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
{code}
So I believe this is still not done. Removing the dev-verify tag.

> Project: Daffodil
> Issue Type: Bug
> Components: Front End, General
> Reporter: Mike Beckerle
> Assignee: Dave Thompson
> Priority: Minor
>
> DFDL v1.0 prohibits definition of recursive "types". Recursive schemas can
> actually be created by way of elements with types, element references, or
> group references.
> A check needs to be in place to issue an SDE if recursive schema definition
> is detected.
> (As of creation of this bug, nothing is checking for this. Need to create
> test cases that plumb recursion through all/many of the various ways it can
> be created, and be sure the SDE is detected.)
