XMLB list of DDL functions to create

XML database schema > Roadmap > Creating new DDL functions > List of DDL functions to create

---

This page will be used to list and track the process of implementation of the new DDL functions available under Moodle 1.7.

This document can be outdated in the future, if new DDL functions arrive, and no efforts to keep it updated will be done. Its primary goal was to have the initial list and to track the work performed, by using the Done tag. Interim process can use the Work In Progress tag.

You always can view, in this link, the actual list of available DDL functions.
