Mike Beckerle updated DAFFODIL-2798:
------------------------------------
Priority: Minor (was: Major)
> No warning on unused dfdlx properties on xs:enumeration
> -------------------------------------------------------
>
> Key: DAFFODIL-2798
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2798
> Project: Daffodil
> Issue Type: Bug
> Components: Front End
> Affects Versions: 3.4.0
> Reporter: Steve Lawrence
> Priority: Minor
>
> Say we have a schema like this (note that dfdlx:repValue is an intentional
> typo and should be dfdl:repValues):
> {code:xml}
> <simpleType name="rep" dfdl:lengthKind="explicit" dfdl:length="1">
> <restriction base="xs:string" />
> </simpleType>
> <simpleType name="value" dfdlx:repType="ex:rep">
> <restriction base="xs:string">
> <enumeration value="ZERO" dfdlx:repValue="0" />
> <enumeration value="ONE" dfdlx:repValue="1" />
> <enumeration value="TWO" dfdlx:repValue="2" />
> </restriction>
> </simpleType>
> <element name="root" type="ex:value" />
> {code}
> Because *dfdlx:repValue* is a typo, Daffodil ignores it--we do not error on
> unknown extension properties because those properties may be used for other
> DFDL implementations. But with this property being ignored, it can leads to
> unexpected behavior or even confusing SDE's if the typo is not discovered.
> Because it is ignored, we should output a warning which helps user discover
> the error. But in this case, with the unknown property being on an
> enumeration, no warning is generated.
> It looks like the issue is that we only check for unused properties on Terms,
> but xs:enumeration is not a Term so we do not check them. Ideally this logic
> would be moved to something more generic so we can warn on all schema
> components instead of just terms.
