Issue 3466, including action items http://www.w3.org/2006/09/20-i18nits-minutes.html#action02 and item http://www.w3.org/2006/09/20-i18nits-minutes.html#action11

Hi all,

I implemented issue 3466, which includes:
- action item http://www.w3.org/2006/09/20-i18nits-minutes.html#action02
Felix to draft a text for the CSS issue. See
http://www.w3.org/International/its/itstagset/itstagset.html#directionality-definition
for the text.
- action item http://www.w3.org/2006/09/20-i18nits-minutes.html#action11
Felix to implement http://www.w3.org/Bugs/Public/show_bug.cgi?id=3466.
This encompasses a subsection 3.5 on "Usage of Internationalized
Resource Identifiers in ITS", the delition of conformance clause 2-2 for
ruby / directionality , and the change of references (Ruby and
directionality are only non-normative referenced now).

Cheers,

Felix
