# XML LLSD security regression corpus These inputs exercise the XML LLSD parser's entity boundary. DTD declarations, external entities, and undeclared named entities must be rejected without file or network access and without entity expansion. The structured-data unit tests load every fixture directly. `malformed_nesting.xml` additionally covers crossed container end tags, while `truncated_scalar.xml` guards against parser loops when a scalar reaches end-of-input without a closing tag.
