XMG-based XTAG developed in 2008 by Katya Saint-Amand during her Master thesis at LORIA.
XMG-2-based XTAG This metagrammar is an update of the XMG-based XTAG.
This new version (Simon Petitjean, 2018) provides full compatibility with XMG-2. Modifications are minor, as they include mostly type declarations and constant renaming, which are needed by the stricter type-checḱing of XMG-2. .
