------------------------------------------
Summary: infinite loops when using dfdl:property extra-long form
for property values
Key: DAFFODIL-2022
URL: https://issues.apache.org/jira/browse/DAFFODIL-2022
Project: Daffodil
Issue Type: Bug
Affects Versions: 2.2.0
Reporter: Michael Beckerle
I have a schema where the delimiters and lengthPatterns have quasi-XML syntax
in them; hence, I am using the extra-long-form annotations e.g.,
{{{
<xs:annotation><xs:appinfo source="http://www.ogf.org/dfdl";>
<dfdl:element>
<dfdl:property name="initiator"><![CDATA[<rdf:RDF%SP;]]></dfdl:property>
</dfdl:element>
</xs:appinfo></xs:annotation>
}}}
I am finding that compiling the schema seems to go into an infinite loop.
Even an egregious error like forgetting that <dfdl:property...> must appear
inside a <dfdl:element> results in infinite loop, not a diagnostic message.
So there are bugs here to chase down. We need a "torture test" for this
dfdl:property style. It's for exactly the use case I have here... where the
property values are "unfriendly" to XSD syntax.
