Detailed Description

XML parsing and document model support, top-level objects are donner::xml::XMLParser and donner::xml::XMLDocument.

A structured libFuzzer target for donner::xml::XMLParser that generates syntactically-correct XML with random DOCTYPE/entity constructs, attributes, comments, CDATA, processing instructions, and nested elements.

The goal is to reach deep paths such as consumeAndExpandEntities() and to validate the mitigation against exponential-growth entity attacks (e.g. "Billion Laughs").
