2 * relaxng.c : implementation of the Relax-NG handling and validity checking
4 * See Copyright for the status of this software.
6 * Daniel Veillard <veillard@redhat.com>
11 * - add support for DTD compatibility spec
12 * http://www.oasis-open.org/committees/relax-ng/compatibility-20011203.html
13 * - report better mem allocations pbms at runtime and abort immediately.
