Mike Beckerle commented on DAFFODIL-2550:
-----------------------------------------
We can now reproduce that even in a schema where no element ever has a target
namespace, so every element declaration is in no-namespace we still get
`xmlns=""` scattered around the schema.
These schema uses target namespaces for files that define types and groups
only. Those files all have `elementFormDefault="unqualified"`. The single file
which defines global elements has no namespace.
> xmlns="" not minimized away in two CLI tests.

> Key: DAFFODIL-2550
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2550
> Project: Daffodil
> Issue Type: Bug
> Components: Middle "End"
> Affects Versions: 3.2.0
> Reporter: Mike Beckerle
> Assignee: Steve Lawrence
> Priority: Major
>
> Changes in [https://github.com/apache/daffodil/pull/600] clean up things a
> lot, but there is one mystery change in behavior.
> Two CLI tests now add an xmlns="" to an inner locally-declared element which
> has a unqualified name.
> This seems like incorrect namespace binding minimization, possibly.
> Rather than hold up the merge of PR 600 (which is a big change set, so needs
> to be merged real soon now) this ticket is to investigate this issue of the
> two CLI tests and the xmlns="" that seems unnecessary.
> Note that we've suspected there could be bugs in namespace binding
> minimization for a while now.
> The two CLI tests are:
> * test_CLI_Debugger_InfoHidden_1
> * test_CLI_Debugger_InfoHidden_2
>
