Mike Beckerle created DAFFODIL-2800:
---------------------------------------
Summary: appinfo annotations with distinct source are being
misinterpreted as DFDL annotations.
Key: DAFFODIL-2800
URL: https://issues.apache.org/jira/browse/DAFFODIL-2800
Project: Daffodil
Issue Type: Bug
Components: Front End
Affects Versions: 3.4.0
Reporter: Mike Beckerle
This bug prevents use of annotations other than DFDL annotations in schemas.
This makes it impossible for me to use my XSAT2 schema scanner to check for
problems in DFDL schemas because the special annotations XSAT2 supports are not
being ignored by Daffodil.
I have this type which carries a special annotation that is NOT a DFDL
annotation:
```xml
<xs:simpleType name="tHexBinary" dfdl:lengthKind="explicit">
<xs:restriction base="xs:hexBinary">
<xs:annotation>
<xs:appinfo source="urn:com.owlcyberdefense.xsat2">
<xsat2>
<nonRemediation>
This type is used only by DFI 9100 and DFI 4242 which are
defined to be opaque fixed length byte strings by the VMF
specification.
</nonRemediation>
</xsat2>
</xs:appinfo>
</xs:annotation>
</xs:restriction>
</xs:simpleType>
```
The source attribute indicates this is about something that is NOT DFDL.
Note that the xsat2 and nonRemediation attributes do NOT carry a namespace
prefix. That may or may not be important.
I get compilation errors like:
```
