Mike Beckerle commented on DAFFODIL-2917:
-----------------------------------------
Hmmm. If a path step or any reference to an element name, is unqualified, and
there is a default namespace defined, then I think that path step is always a
default namespace reference. I don't know why we would ever interpret that
situation as noNamespace.
In order to reference something in noNamespace, you have to use an unqualified
path step and not have a default namespace.
So I think there is no need for a tunable, nor property, except... for backward
compatibility with our current behavior.
Right now an unqualified path step is assumed to be no namespace, regardless of
whether there is a default namespace defined. I think this is incorrect, but it
is the default behavior of unprefixedPathStepPolicy tunable.
> tunable unqualifiedPathStepPolicy seems unnecessary - deprecate it

> URL: https://issues.apache.org/jira/browse/DAFFODIL-2917
> Project: Daffodil
> Issue Type: Improvement
> Components: Front End
> Affects Versions: 3.8.0
> Reporter: Mike Beckerle
> Priority: Major
>
> The tunable unqualifiedPathStepPolicy seems unnecessary
> This policy can be based on the elementFormDefault of the lexically enclosing
> schema where the path appears.
> If the elementFormDefault is unqualified, then a path step with no prefix
> should be assumed to have no namespace.
> If the elementFormDefault is qualified, then a path step with no prefix
> should be assumed to be in the default namespace (if defined) and
> no-namespace if no default namespace is defined.
> These correspond to the unqualifiedPathStepPolicy values of noNamespace, and
> preferDefaultNamespace respectively. The default for
> unqualifiedPathStepPolicy is noNamespace which would correspond to the
> elementFormDefault default value of "unqualified".
> The third value of unqualifiedPathStepPolicy, which is "defaultNamespace" is
> problematic because the schema may have none.
