        This document provides information about the XML schema implemented in this release of xml2rfc, and the individual elements of that schema.  The document is generated from the RNG schema file that is part of the xml2rfc distribution, so schema information in this document should always be in sync with the schema in actual use.  The textual descriptions depend on manual updates in order to reflect the implementation.
