Michael Beckerle commented on DAFFODIL-2141:
--------------------------------------------
This problem is responsible for the TDML cross test runner bug:
https://github.com/OpenDFDL/ibmDFDLCrossTester/issues/8
because the infoset being output from the parse has the wrong namespaces, the
IBM DFDL cross-tester feeds the wrong element to IBM DFDL which is unable to
unparse it.
The rather gross workaround is to use elementFormDefault="qualified".

> Key: DAFFODIL-2141
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2141
> Project: Daffodil
> Issue Type: Bug
> Components: Back End
> Affects Versions: 2.4.0
> Reporter: Michael Beckerle
> Priority: Major
> Fix For: 2.4.0
>
>
> If you run the CSV example, the Infoset XML from parse looks like:
>
> {code:java}
> <file xmlns="http://example.com";>
> <header xmlns="">
> <title>last</title>
> <title>first</title>
> <title>middle</title>
> <title>DOB</title>
> </header>
> <record>
> <item>smith</item>
> <item>robert</item>
> <item>brandon</item>
> <item>1988-03-24</item>
> </record>
> <record>
> <item>johnson</item>
> <item>john</item>
> <item>henry</item>
> <item>1986-01-23</item>
> </record>
> <record>
> <item>jones</item>
> <item>arya</item>
> <item>cat</item>
> <item>1986-02-19</item>
> </record>
> </file>
> {code}
> The above is simply wrong, because the elementFormDefault is 'unqualified',
> so the record element is a local element declaration in no namespace. The
> above sets the default no-prefix namespace to the example namespace, and that
> definition applies not to the header element, which overrides it, but to all
> the record elements and their children.
>
> This is simply incorrect. Every record element needs the same xmlns="" on it
> as well as the header element.
> A better output infoset would reuse the "ex" prefix definition from the
> CSV.dfdl.xsd schema and output this:
>
> {code:java}
> <ex:file xmlns:ex="http://example.com";>
> <header>
> <title>last</title>
> <title>first</title>
> <title>middle</title>
> <title>DOB</title>
> </header>
> <record>
> <item>smith</item>
> <item>robert</item>
> <item>brandon</item>
> <item>1988-03-24</item>
> </record>
> <record>
> <item>johnson</item>
> <item>john</item>
> <item>henry</item>
> <item>1986-01-23</item>
> </record>
> <record>
> <item>jones</item>
> <item>arya</item>
> <item>cat</item>
> <item>1986-02-19</item>
> </record>
> </ex:file>
> {code}
