---------------------------------------

             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:
```
[error] Schema Definition Error: Error loading schema due to org.xml.sax.SAXParseException; lineNumber: 56; columnNumber: 24; cvc-complex-type.2.4.a: Invalid content was found starting with element 'xsat2'. One of '\{"http://www.ogf.org/dfdl/dfdl-1.0/":assert, "http://www.ogf.org/dfdl/dfdl-1.0/":choice, "http://www.ogf.org/dfdl/dfdl-1.0/":defineEscapeScheme, "http://www.ogf.org/dfdl/dfdl-1.0/":defineFormat, "http://www.ogf.org/dfdl/dfdl-1.0/":defineVariable, "http://www.ogf.org/dfdl/dfdl-1.0/":discriminator, "http://www.ogf.org/dfdl/dfdl-1.0/":element, "http://www.ogf.org/dfdl/dfdl-1.0/":enumeration, "http://www.ogf.org/dfdl/dfdl-1.0/":format, "http://www.ogf.org/dfdl/dfdl-1.0/":group, "http://www.ogf.org/dfdl/dfdl-1.0/":newVariableInstance, "http://www.ogf.org/dfdl/dfdl-1.0/":sequence, "http://www.ogf.org/dfdl/dfdl-1.0/":setVariable, "http://www.ogf.org/dfdl/dfdl-1.0/":simpleType, WC[##other:"http://www.ogf.org/dfdl/dfdl-1.0/"]}' is expected.
