Hello,
Glad to hear you have found the tutorial useful, the core team are working on XHTML compliance, but progress will be slow. Their main concern is for backwards compatibility and to ensure that any small changes will not break users portals. So they will be keen to extensively test any of these changes to ensure backwards compatibility.
Things are starting to progress however with new features such as the Doc Type function.
Also check this forum post where I have just outlined how to ensure XHTML compliance with the text/HTML module:
