Incidentally, if you don’t know what any of this means, you do not need to worry. But if you are really interested then it is a DTD (Document Type Definition) for the XMLised output of Valgrind’s Lackey tool, as patched by me to also output thread (Posix pthread) data. The original – version 0.1 – DTD (which does not account for thread data) can be found in the lackey_xml git repository.
